Polyethylene, e.a., obtained by means of old methods, had a
melting temperature of 1250, whereas obtained by the new methods
it exhibits a melting temperature of 1700. Amongst the high-
temperature resistive polymers, polytetrafluorocthylene is
of interest. Unsaturated polyether-resins viere lar~-ely used
for the manufacture of lar e-size products like boats and others.
The epoxy-resins (6poksidnyye smoly) will play an important
role in the manufacture of synthetic materials. The research
work carried out in the field of the 3yntheris of organic
fluorine -containing polyneric compounds should also be intensi-
fied. The production of inoculated and block polymers is also
of great interrat. A.11.11esmeyanov and his collaborators are
occupied with the investiration of forrocene compounds. The
synthesis of ort;anic polymers which does not only utilize
chemical bonds, but also intercomplex bindin~;s, is of -reat
interest. Further work carried out in the field of the synthesis
of new polymers which are di9tinguiched by high mechanical
strengtht cood electrical properties and which are moisture-
resistant are considered to be of --pecial importance. R would
also be of importance to produce such polymers that would re-

ABSTRACT: A classification of faults occurring in electrical machines
shows, that about llo~~ are caused by a fault in the electric
insulation. This analysis shows furthermore, that the ave-age
life of electromotors until a general repair is 315 years. A
combination of the valuable properties of polymers with the
thermal stability of glass fiber, mica and~asbestos permits to
increase considerably the life of electrotechnical equipment.,
The introduction of this new insulation in pit machinery re-
sulted-in a reduction of material expenditure and an increase
in coal production. At present hiE;h-molecular compounds are
produced on a wide range in the USSR for various branches of
indu'stry..The most important criterion for the evaluation of
the propek-ties and the range of application of an electric
insulation is the maximum heat resistivity- Some examples are

different grades of msulation quality. The thermal resist-
ivity (temperature stability) of organic, fluoro-organic,
o.rganosilicon, and of synthetic polymers is dependent upon the
chemical composition and the structure of the polymers. Poly-
organosiloxanes and polytetrafluoro ethylene exceed all other
organic polymers as to thermal resistivity. Computations of
the activation energy showed, that it is equal to 36 kcal/mol
at a destruction by thermooxidation and 33,0 kcal/Mol at an
electric disruption of the coatings. In organic polymers this
energy amounts to 25 17 kcal/tAol in glycol sebacinate in the
first case and 26,0 kcal/Mol kn glycol terephthalate. In
the second case it amounts to 24,8 kcal/Mol in glycol-
teraphthalate. The activation energy is somewhat lower in
other organic polymers. Besides, polyorganosiloxanes exhibit
high electric properties and are damp-proof. The highest
thermal resistivity among elastic organic polymers is shown
by polyesters on a basis of polyatomic alcohols, of terephthalic,
isophthalic, and adipinic acid and polyesters modified by
polyorganosiloxanes. For electric insulation with an operational
temperature of 12oOE polyvinyl acetal resins, polyurethanes,
Card 2/3 epoxy resins must be extensively used in the production of

lacquer wires. Polyesters with a linear molecular structure
of the "Lavsan" type must be primarily used for the slot in-
sulation of machines, for wire insulation etc. Polyamide
resins must be used for grade A insulation at an operational
temperature of 1050. At this temperature mostly isotactic
polymers must be used. There are 2 tables and 5 references,
3 of which are Soviet.

ABSTRACT: There have been little publioations on organo-silicon liquid
polymers with polar groups in the organic radical. In the intro-
duction the authors mention various papers (Refs 1-6) dealing
with these problems. The synthesis of liquid polyorganosiloxanes
with amino nitrogen in the organic radical at the silicon atom
is not only of theoretical. interest but has also practical
value (the production of polymer liquids of valuable technical
properiles). In the present paper the authors describe the
production of organosilicon liquid polymers (of the degree of

ABSTRACT: In the previous papers the authors showed that triethyl-
silanol can react with aluminum to form aluminum
triethylsilanolate with the liberation of hydrogen.
The high reactivity of hydroxyl-containing or.-anosilicon
compounds toward metals can only be explained by the
fact that the silicon atom in these compounds exhibits
a high degree of polarizability. The authors were
interested in investigating the reactivity of several
polymers of organosilicon compounds which had hydroxyl
groups at the silicon atom. It was found that in the
reaction of these compoundn with motallic sodium, magne.-lu'MI
and aluminum that hydrogen was liberated -,-id a mt~tal

taining organosilicon compounds depends upon the re-
sistivity at these hydroxyl groups. Compounds which
enter into intermolecular condensation reactions easily
do not react with metals. On the other hand, hydroxyl
groups which are resistive to condensation reactions
react relutively easily with metals. There are 6 tables
and 4 references, 2 of which are Soviet.

ABSTRACT: The chomiztry of the organic siliconcompounde is one of the
younc.cat branches of technology. Its development started in
USSR in tho years 1935 - 1938. These compounds which are at pre-
sent produced in industry, are used in the various fields of
national industry in the form of heat and frost-resisting ma-
terials, of electroinsulating and refracttory lace as well as
so-called sii2conorganie fluids$ oila# lubricants, rubbers and
resins. At present excellent electric insulating materials are
produced on the basis of siliconorganic resins as well as dif-
ferent lace which can stand a working-temperaturo of 18o-2oo 0C
and a short temperature of 350 - 4000C. The siliconorCanic
rubber stands temperature fluctuations of -6o 0 up to + 2500C.
Fluid siliconor~;a)iic polymers are well known. An exceptionally

properties make it possible to use those polymers in the
various fields of technology. In most of the cases the fluids
are used as lubricants. Thanks to the siliconorganic oil, the
weight of the apparatus can be reduced in the hydratilic system
of the aeroplanes. The siliconorganic fluids are used in the
case of viaorapparatus, motors, timing relays, radiolocation
devices of the navyt etc. They can also serve as lubricants for
sintermolds as %yell as molds for rubber substances. One of the
most important possibilities of application is the covering
and ooo.king of various materials with those fluids in order
to make the material water repellent. Lenses and optic Classes
are also being covered, with those fiuids in order to Guarantee
a better light transmittance and to protect them against at-
mospheric influences. Cement, soaked with niliconor~;anic fluid
makes the brick wall waterproof. Because of their high surface
activity those fluids can be used to avoid foam formation in
various media. Polyorganic siloxanes are used as heat and
weatherresisting corrosion preventives for steel, aluminum and
other metals. The polymers described in this article are not

ABSTRICT: The so-called organosiloxanes have been known and polymerized
for.,qu.ite some ti=-, - The investigation of these sub-
stances proved to be extremely important since they show high
thermal stability and viscosity, qualities required in modern,
technics. They are substances with the inner component - 4--o-li-
framed by radicals. The formation of the poly-siloxanes takes
place in general as followsi first, complete or partial hydro-
lysis of organosilanes, and then polycondensation

under the action of acid or alkaline catalysts. Hydrolysis is
carried out continuously according to the countercurrent principle.
Basic products the radicals of which are branched (increase in
stability) are stressed. Cyclic radicals are not especially suit-
Card 1/3 ed for this purpose. Certain methods of producing polymers are

Xleuntal-organic PoyWrIc CCUPWAda SOV/74.~27-11-1/5
mentioned. One method consists in forming polymers from monomeric
organosilicic acids, or from organosilicic compounds with terminal
OH groups with alkyl halides under a separation of HCI. Thermo-
oxidations and polycondensations with atmospheric oxygen have been
investigated as well as oxidations by applying a sound field.
Linear polymeric chains were equally synthesized from cyclic mono-
mers of orgenosiloxanes. The highest molecular weigh'. which could
be obtained was 1 290 000. Plastic substances have a molecular
weight..:of 144 000 - 408 000. All molecular weights lower than the
above mentioned belong to liquid substances. By means of the
Riggin equation (Ref 195) an asstunption on the nonuniform structuxe
of the polymers was made. Furthermore, polyorganic metallic si-
loxanes are mentioned, the chain unit of which is based on the
following basic schemei R
i - 0 - M - 0 i - 0
i.e. polyorganic aluminum siloxanes, Lan si9loxanes, siloxanes con-
taining titanium, tin, lead, zir-onium, antimony, phosphorus, ger-

They contain metals directly linked to the radical. The methods
of their production are not yet sufficiently elaborated. The
formation of an aluminum resin, in which compounds with affiliat-
ed chains are formed over aluminum,is of interest. Also a boro-
ether with an ionic-basio component is mentioned.
It is said in general that ramified polXmers have higher stabiliv.
Stability, solubility, viscosity equally depend on the diversity
of the substituted radicals (Tables). There are 5 figures,
5 tables, and 320 references, 46 of which are Soviet.

ABSTRACT; Polyorganosiloxanes are obtained by the hydrolysis of
alkyl(aryl)haloidsilanes or alkyl(aryl)alkoxysilanes with
subsequent condensation of the products of hydrolysis. During
the hydrolysis, reactions occur which lead to the formation
of linear or cyclic polymers. With excess water cycl-ic polymers
in acidous medium result with good yields. In the hydrolysis
of the difunotional monomers (of dimethylahlorosilane,
phenylmethyldichlorosilane) low-molecular cyclic products
were.serrated -trimers, tetramers and higher eyoles
(ref I . The cyclic compounds obtained can regroup in the
presence of catalysts (sulfuric acid, antimony pentachloride,

polymerization of the cycles obtained from dimethylchloro-
silane occurs with an action of alkalies according to the
given scheme (final product
HOSJR2OSiR2OSiR20-).
Recently, it was found that in the hydrolysis of three-
functional compounds in acidous medium also cyclic polymers
are formed. In the hydrolysis of 4bthyltriethoxysilano and
pentachlorophenyltrichlorosilane crystalline cyclic polymers
of the mentioned cubic structure were separated: in the
common hydrolysis of phenyltrichlorosilane with dimethyl-
dichlorosilane in acidous medium also cyclic polymers of
the mixed type (see formula A) are formed. ks the.conversions
of tri- and di-functional alkyl (aryl)haloidsilanes iajo
polymers are of great interest the authors tried to explain
the reaction of alkaline catalytic polymerization of cyclic
compounds obtained in the hydrolysis of phenyltrichlorosilane
as well as the products of the common hydrolysis of phenyl-
Card 2/3 trichlorosilane with dimethy1dichlorosilane. It was found that

ABSTRACT: blost Bolyorgano-silol-'anes requirc a curiar~ temperature
of about 200 C and it is, thereforc, desira).-.le to dcvelop
materials of this typc tuha~ can be cured at lover temperatures.
This can be done by the ust, of catalysts, particularly the
naphthenates of lead, magnesium, cobalt and zinc and also
oleates of various metals. In the enarnels, that were developed,
the binder consisted of poly-methyl-n'-I-enyl-siloxane reains
which are products of combined hydrolysis and subsequent Inoly-
condensation of di- and tri-functional methyl ~phenyl) h--loid
silanes.
In the presence of catalysts, poly-methyl-phenyl-siloxanes

Bi-valent metals in the catalysts promote oxidation but this
is not the main process of hardening of poly-methyl-phenyl-
silo6anes in the presence of catalysts at temperatures up to
150 G. This statement is confirmed by the f~L-ct that salts
of metals which cannot form hiGhcr oxides nevertheless have
some catalytic effect. Poly-condensation resultinL from the
interaction of hydroxyl groups is always accompanied by a
reduction in the content of QH groups as the viscosity of the
polymer increases. Roviever, detuermincztion of OH groups and
water in the polymer durin.- the -process of interaction bgtiveen
poly-methyl-phen,yl-siloxanes and lead naphthenate at 20 C
shows that increase in the viscosity of the polymer solution
is not accompanied by reduction in the quantity of hydroxyl
groups (see Table 1). Therefore, poly-condensation processes
do not occur at this temperature.
Therefore, the main reaction durinU hardening in the presence
of catalysts at low temperature must be re-Grouping of the

whi4, in the presence of catalysts harden at a temperature of
120 C, were developed on the basis of poly-methyl-ohenyl-
siloxane resins modified by polyether. The Properties of
these products are described.
The duration of hardening depends on the type and quantity of
catalyst. It will be seen from Table 2 that the most active
catalysts are lead naplithenate and the naphthenate of lead and
manganese. Table 3 shows that the use of hardening accelerators
leads to some reduction in the thexinal elasticity of the resin
films. The naphthenate of lead and manganese C;ives the best
overall results. 0
The low-temperature-dryin,-, enarels are very hard. At 120 C1
in the presence of naphtlienate of lead and j,,,,anE,,anese, they 0
dry much harder than enamels dryinU at temperatures of 180 0
(see Fig.4). The use of surfcce-lactive nrt~rials as catalysts
improves the adhesion of the lacquers to steel.

from Table 5, which pives the volume resistivity and electric
strength of enamel films. The good properties are well main-
tained after prolonged thermal aCeing, as will be seen from
Fig.6- The dielectric properties of the enamels are little
affected by temperature or humidity. Pesistivity and electric
strength curves as functions of temperature and time are
given in Figs. 1, 2 and 3.
The resins harden slowl; in the presence of catalysts even
at a temperature of 20 C, but piCnentation retards this pro-
cess. The data given in Table 7 and FiL.4 shou that in the
presence of a low-activity accelerator, the viscosity of enamel
11K)-19 hardly changes after several months and if a more
active catalyst, such as lead naphthenate or naphthenate of
lead and manganese, is used, the increase of viscosity and
the formation of gel takes place much more slo%,.ly than in
unpigmented lacquer. In practice, it is best to mix in the
accelerator imi,ediately before use.
These lacquers are rccoriLiended for the insulction of electrical
macqnes workin[~ in moist conditions at temperatures up to
180 C.

ABSTRACT: For the impregnation of radio COTBDoncn-ts, compositions
based on unsaturated polyesters and epoxy resins have been
used successfully. I:- present, Tairly extensive industrial
use is made of high-molecular-zeight compounds obtained fron
di-isocyanates. Di-isocyanates are very reactive, and by
rev.ctinG them faith polyfutictional hydrox~ cor~7~ounds, poly-
urethanes are formed. These substances do not melt, do not
dissolve in organic solvents and the reaction takes place
r,,ithout formation of subsidiary products; hence they have
been used for casting insulation.
The authors have synthesised and studied thie mechanical and
electrical properties of polyurethane polymers obtained by
the co-polyiiierisation of di-isocyanates and castor oil in
ronomers such as styrol, di-chlor styrol, acrylcnitrile, mothyl

PERIODICAL: Tr. Vses. elektrotekhn. In-ta, 1958, No. 62, PP. 51-15
TEXT: The direct synthesis of organic chlorsilanes1was sugg6sted by
Myuller and Rokhov in 1942-1945. The method is based on-the property of elem64-
tal Si to enter into a reaction with halogenes and organic halides at higher '
temperatures, forming chlorsilanes and organic chlorsilanes. Cu is one of the
best catalysts in this direct synthesis. The authors discuss the results of
experimental data of the direct synthesis obtained at VEI in 1946. Ferr6silicon
can be used instead of pure Si. The synthesis of ethyl, vinyl, and phenyl
chlorsilanes is described briefly. A theory of the direct synthesis of organic
chlorsilanes as a heterogeneous catalysis process at high temperatures has not
yet been developed. There are 13 references. A. 0. M.

ABSTRACT: Properties of organic and s Iilico-organic polymersiare discussed. The struc-
ture of molecules exercises a great influence on properties of polymers.
An increased frost-resistance and poor mechanic properties of silico-or-
ganic polymers are exp"Ined by low polarity and a weak interaction of mole-
cules. The relaxation character of dielectric losses of silico-organic
polymers caused by temperature is determined by the polar bond - Si - 0
The silico-organic polymers compared with the organic polymers, have an in-
creased thermoelasticity. Properties and fields of application of some di-
electrics based on organic and silico-organic polymers are briefly described,

pp. 1124-1127 (tIRS0.
ABSTRACT: Tha fusibility and solubility of polymers in organic solvents
are considered to be dependent on the molecular structure of
the chains. Polymers with a linear structure are soluble and
meltable by heating, regardless of their molecular weight. The
branching of the chain, viz. the formation of laced (,sshity~e
structures and spatial structures makes the polymer Jo3e-
these properties. This dependence concerns all polymers. The
a,.thors tested the synthesis of polymers which were readily
soluble in non- or slightly-polar solvents but which did not
melt when heated. The results obtained by thotu-ough investigan
tions.show that no polymers with the aforesaid properties can be
obtained with the production of cyclic poly-organo-siloxanes.

responds to a cyclic structure of the i;olecules, was proved
during the hydrolysis of phenvltrichlorosilane. Such polymers,
howevers are soluble in organic solvents and melt when heated.
A long lasting heating of the polyphenyl-ailoxanes at 25o0C
and above c7auses an increase of the melting temperatures, but
the polymer loses its solubility at the same time. The polymeric
molecule grows apparently in first line due to bursting of the
rings and their polymerization under the formation of structures
which are laced. For increasing the melting-temperature of the
complicated cyclic polyphenyl-siloxanes, aluminum was introduced
into the molecule of the polymer. Aluminum-s iloxane reacts with
phenyl-trihydroxy,-gilane by precipitating water. A further con-
densation at the cost of the hydroxyl-;g~oups under formation a
polymer with a molecular weight of 599o, a content of hydroxyl-
groups of 5.,50/o and a ratio si. Al - 4,1. The obtained aluminum-
phenyi-siloxaneeis a colorless, brittlei vitreous substance which
does not melt with heating up to 5ooOC and does not siftter either
(figure'l). It is readily soluble in; benzene, toluene, acetone,
ethanol, chlorobenzene and carbon tetrachloride, yet insoluble in
petroleum ether and white spirit. Though the content of GH-groups
in the polymer decreases from 5,53 to 2,70/0 with a heating at

ABSTRACT: In investigating the influence of the triaryl-, trialkyl-, and
mixed tri(alkyl-aryl) siloxy-groups on the properties of the
compound mentioned last j.n the title tl,e authors found it
necessary to syrthesize -come new derivatives of the latter, i.
e. those which contain aromatic and aliphatic radicals in the
silicon atom. In order to produce mixed tetrakis/tri(aryl-alkyl)
siloxy/titanium corpounds the authors synthesized a number of
organosilicon compounds. The latter served as initial products
for the production of tetrakis/tri(alkyl-aryl) siloxy/titaniam
compounds. Pheryl-dimethyl chlorosilane and methyl diphenyl
chlorosilane were formed according to the Grignard (Crinlyar)
reaction. For the production of alkyl-aryl silanols the latte-r

hydrolized by means of ammonia solutions. The total scheme of
the compounds produced is illustrated by 3 equations. All com-
pounds produced according to,this scheme were isolated at each
stage of the process and their empirical formulae and the main
constants rare determined (Table 1). The production of tetra-
kis/tri(alkyl-aryl) siloxy/titanium compounds was carried out
by two methods-, 1) BY the action of titanium tetrachloride on
diphenyl methyl silanol in the presence of ammonia. Thus$ tetra-
kis-(diphenyl methyl siloxy) titanium was produced. At room
temperature it is a high-boiling liquid. 2) Tetrakis (dimethyl
phenyl siloxy) titanium was produced by means of the reaction of
sodium dimethyl phenyl nilanolato with titanium tetrachloride
(a scheme is given). There are I tabl e and 6 references, 2 of

ABSTRACTs In the USSR organo-silicio resins (OR) are largely used-in the
production of heat-resistant varnishes. At present, there
exist several types of (OR), but only polymethylsiloxane-#
polyphenylsiloxane-, polyohlorophenylsiloxane-, polymethyl-
phenylsiloxane -, and polyethylphenylsiloxane resins are being
used in pure state and changed with organic polymera. Tempera-
ture resistance, hydrophobic properties/as well as chemical
and oxidation resistance are the most important properties of
the varnish- and resin films produced on the basis of (OR).
Organo-silicic resins and varnishes exhibit good dielectric
properties depending only little on temperature and current
frequency. For this reason they are used for electrical

combination and application of (OR) for corrosion-proof coatings
the heat-resistant enamel varnish Nr 9 and the polydimethyl-
phenylailoxane enamel varnishes PRKE-13 and PRKE-15 are
preferably used in Soviet industries (Ref 31). Plastics on

as for the production of foam plastics. For their production
polymethylphenylBiloxane resins K-40 and K-47,as well as modi-

ABSTRACT: In the present paper the hydrolysis of chioro phenyl-tri-
cbloro silanes in aqueous media at 36-380 was investigated.
Jn all experiments solid, brittle polymers were obtained which
are easily soluble in organic solvents and possess distinctly
marked melting points, After long heating at 2000 they retain
their thermoplastic properties and good solubility. The ana-
lysis of the'polymers obtained with reGard to the functional
groups indicated the absence of chlorine and the hydroxyl
groups combined with the silicon atoms, X-ray investigations
revealed the occurrence of a crystalline phase. The polymers
melt within a small tempezuture range which in typical of
crystalline substances (Table 1), On the basis of analytical
data and the determination of the molecular weight the

an average polymerization degree of n 5. Irrespective of
the small melting range, they possess a considerable poly-
dispersion. This might be the cause of the difficult separation
of crystalline products froin polychloro phenyl oiloxanes.
Only in the case of polypentachloro phenyl siloxane 4 crystal-
line fractions could be separated, These individual crystal-
line polyners have a steric-cyclic structure (C1 5C6 sio 1,5)n'
Cyclic products not only of steric but also of planar struc-
ture are probably formed there. The thermoplastic properties
of the polymers obtained on hydrolysis of phenyl- and chloro
phenyl-trichloro silanea in the case of water excess are due
to the-fornation of cyclic products of steric structure.
Such cyclic products have no functional groups and can there-
fore be transformed into buMup or btdltup-steric higher
polymer structures by opening of the cycles only. As was shown
by the thermal aginC of the polyorgranosiloxanes obtained from
trifunctional monomers, the breaking of the

quently the stability of the polymers obtained by hydrolysis
of phenyl- and chlorophenyl-trichlorosilanes against is,
contrary to thermal conversions, deternined by steric cycles.

ABSTRACT: It is known from publications that the reaction of the organic
alcohols with isocyanates proceeds without separation of
by-products. A* WUrtz (Ref 1) was the first scientist who
proved that the reaction is accomparded by a migration of the
hydrogen atom of the hydroxyl group to the nitrogen atom of the
isocyanogen group. The authors found (Ref 2), that the trialkyl
hydroxysilanes react in the same way with the diisocyanates as
with the organic alcohols according to the scheme:

ABSTRACT: In the paper under review the authors give data concerning
their work during 1947 in the field of the preparation of
liquid polydiethylsiloxanes from diethyldiethoxysilane and its
mixtures with triethylethoxysilane. It was the objective of
this work to synthesize polymeric liquids free from impurities
of those polymers which contain ethoxy groups in the molecule.
The hydrolysis of diethyldiethoxysilane in an aqueous medium
at 1000 resulted in the formation of the diethyldioxy- and
oxyethoxysilanes which, in turn, were transformed into pol
diethylsiloxanes of cyclic and normal structures (Scheme 1~-.

Polydiethylsiloxane Liquids. I. The Effect of Sulphuric Acid on Diethyldi-

the ethoxy group (b) in the molecule could not be avoided. The
synthesis of polydiethylsiloxanes free from ethoxy groups on
the basis of the hydrolysis products of diethyldiethoxysilane
was carried out by means of a reaction with 93-100% sulphuric
acid at 20-500 as well as with 95-99% formic- or acetic acid
at 60-1000 according to scheme (II). When sulphuric acid was
used the fractional composition of polydiethylsiloxanes changed
abruptly toward the formation,ofpolymers of a higher average
moledular weight (Scheme III). The carboxylic acids did no'.
cause a regrouping of the cyclic polymers (Scheme II, Table I).
On the basis of what has been reported so far it was possible
to assume that the synthe3iS Of polydiethylsiloxanes free from
polymeric impurities containing ethoxy groups in the molecule
by the action of concentrated acids (esp. sulphuric acid)
upon diethyldiethoxysilane folloivs the general scheme (IV)

ABSTRACT: In continuation of the preceding paper (z0C 1959,29,1270) the
data concerning the reactions of phosphoric- and boric acid
with ethylethoxysilanes are described in the present article.
It was shown that, like sulphuric acid, phosphoric acid react-
ing with diethyldiethoxysilane results in a formition of poly-
diethylsiloxanes free from impurities of normal polymers with
ethoxy groups in the molecule, and in the formation of acid
ethyl phosphates. This formation is brought about at a molar
ratio of diethyldiethoxyailane to the acid of 3:2 UP to 1:2.
There was no neutral eater to be found in the reacticz nroducts.

sulphuric acid (scheme I) the reaction with phosphoric acid ex-
hibits an intermediate stage in which polydiethylsiloxane phos-
phates forml which are stable in the middle of the-reaction ac-
cording to scheme (II). If water influences the reaction pro-
ductp a hydrolysis of the phosphates accompanied by the separa-
tion of polydiethylailoxaneB and acid ethyl phosphates takes
place according to schemes (III) and (IV). It proved impossible
to remove the polydiethylailoxane phosphates since the distil-
lation of the reaction material resulted in their decomposition.
Their presence was proved in three ways. The date obtained sup-
port the assumption that two kinds of polydiethylsiloxane phos-
phates are present in the reaction product (Scheme II). In the
hydrolysis (Scheme III) it may be seen that polydiethylsiloxane
phosphates exhibit a polymeric grouping as soon as the acid
ethyl phosphate is split off. A further condensation results in
non-distillable polymers of high molecular weight. In this hy-
drolysis (Scheme IV) individual polymer components, the cycli-

ABSTRACT: In continuation of the preceding report (Ref 1) the investiga-
tions under review show that the polyalkylsiloxyaluminum phos-
phates are obtainedltrthe polycondensation of the tris-(trial-
kylsiloxy)-aluminum with organo-phosphosilicon compouads ac-
cording to schemes 1) and 2). The riature of the resulting poly-
mers depends on the nature of the organic radical in the sur-
rounding trialkylsiloxane groups. By the condensation of tris-
_(triethylsiloxy)-aluminum with triethylsiloxYphosphinic acid
or tris-(triethylsilyl)-phosphate at 200-2200 polymers were ob-
tained which changed to an unsoluble, not meltable, and solid
state above the afore-mentioned temperature. Under the same

also obtained by the use of trimethylsiloxyphosphinic acid. In
order to confirm the scheme mentioned 2 mols of tris-(triethyl-

phosphinio acid. In this way the condensation product (III) Of
low molecular weight was obtained; hexaethyldisiloxane and wa-
ter were eliminated in quantities corresponding to scheme 2.
The analysis of the product corresponds to the formula given
in scheme 2. By the same condensation, which was, in this case,

ABSTRACTs In the present paper the breaking of the chains was investigatedt

Por this purpose trimethyl borate and tatramethoxy-silane with
a higher concentration of the heavy oxygen isotope 018 (excess of
018 0.40 at%) were prepar~%A. By interaction of tetramethoxy-si-

not the C-0- and Si-O-bonds are brokon, as expected, but the
B-0- and O-C-bonds. Possibly both the interaction of totra-
methoxy-silane with triacotoxy-boron and the interaction of tri-
methyl borate with diethyl-acetoxy-silane proceeds according to
cyclic mechanisms. The reaction, however$ can practically not be
carried out in absolutely anhydrous conditions. Traces of water
in the components or in the reaction medium cause a hydrolysis
of one of the initial components. Methyl alcohol
C113018 H or acetic acid is separated which causes either an
alcoholysis (Ref 4) or acidolysis of the other initial components
and the formation of methyl acetate. Thus the processes covered
by equations (1) and (2) can contain several groups of reactions.

ABSTRACT: The authors concluded from the formation of benzyl, -aethyl
chloro-silanes and acylation of bdnzyl-trimethyl silane thRt
the Priedel-Orafte reaction may be suooesifully applied to the
synihesis of various. b.onzyl eiloxane derive.tives in which AV-he
aromatio nuolous is separated from the silicon atom by the
methyline group. Experlients indicated-that ben'zyl-dimethyl-
chloro-silane is not destroyed in the presence of aluminum
chloride and can be used as initial product for the synthesis
of ~is-(acetobenzyl)-tetrametfiyl-disiloxane. The benzyl-
dimethyl-ohloro silane was prepared according to the Grigriard
reaotion from dimethyl-dichlaro-silpne and bennyl maGnesium

disiloxane has the properties of aliphntic-aromatic ketones
and forms the dinitro-phenyl hydrazone In which case the

the bis-(acetobenzyl)-tetramethyl-disiloxane with sodium
It ypobromide' in alkali the toluic acid is formed which'%vas
idektified in the form-oi its methyl ester. A com,~.:rt,,tiv'ely
6asi-sepa*ration of the bonzyl carb6xy--roup is connected with
the displace 'mant of the reactivi,ty in the system cf the
conjugated nuclear bonds. In consequence of -It-a decrep-aa of
the elQctron density on the silicon nucleus and subsequent
rupture ofthe Si-C-bond takes place under the influence of
nucleothilic agenta- When using alkaline solution,
the oxidation is complete and terep'hthalic acid is formed. The
formation of the p-toluic and torephthalic acid indicates
that the aceto-group comes into para-position with respect to
the methylene gtoup during the Priedel-Crafte reaction.
Properties of the compounds synthesized are given in the
