TITLEs On the Reaction of Organosilico Urethanes and Monohydroxysilanes
With Alcohols
PERIODICALs Zhurnal obahchey khimii, 1959, Vol 29, Nr 8, pp 2698 - 2701 (USSR)
ABSTRACT: As the authors have already shown (Ref 1) the reaction of the
trialkylhydroxyailanes with diisocyanates takes place without
any by-products. In this process the hydrogen atom of the hydro-
xyl group of trialkylhydroxysilane migrates to the nitrogen
atom of the isocyano group while organosilico urethanes are
formed:
.,/NCO NHCOOSiR3
R\ NCO + 2HOSiR3 -----> R~ NHCOOSiR3
These urethanes are very sensitive to hydrolysis with waters

On'the Reaction of Organosilico Urethanes and Mono- SOV/79-29-8-56/81
hydroxysilanes With Alcohols
The present paper shows that these urethanes do not only
react with water but also with alcohols while forming a dia-
mine,a,trialkyl-substititBd ester of orthosilicio acid and of
carbon dioxide. The formation of these products may take place
as follows% organosilico urethane reacts with very small quanti-
ties of water in the alcohol and forms dicarbamic acid and tri-
alkyl hydroxysilane. The unstable dicarbamic acid decomposes
into CO2 and diamine while silane reacts with alcohol and forms
the trialkyl-substituted ester of orthosilicic acid (Scheme 3).
In order to prove this mechanism it has to be found out whether
the trialky1hydroxysilanes can react with alcohols (without
catalysts as well). The experiments showed that these silanes
react with alcohols in the presence of diamine, but also without
diamine, according to the scheme
R3'SiOH + HOR" R3'SiOR" + H20. The reaction was carried
out with methyl-, propyl-, butyl-, and isoamyl alcohol. The
Card 2/3 properties of the new compounds are given in the table. Ex-

FERIODICAL: Zhurnal obahchey khimii, 1959, Vol 29, Nr 8,

ABSTRACT: As the authors showed in a previous paper (Ref 1), benzy1di-
methylohlorosilane easily reacts with acetic anhydride in
the presence of AM 3 while bis-(4-acetobenzyl)-tetramethyl-
disiloxane is formed with a yield of 5C~- In the present
paper this reaction -was used in the synthesis of silicon di-
carboxylic acid and aromatic ketones. Benzyldimethylchloro-.
silane and the acylating compounds (succinic acid - phthalic
anhydride and benzoylehloride) were used as a basis (Scheme 1).
By means of the reaction the best yield was achieved in a
benzene medium (50-6Wo). The acylation of benzyldimethyl-
chlorosilane with benzoylchloride leads to the aromatic di-
Card 1/2 ketone according to scheme 2. Bis-(benzoylbenzyl)-tetramethyl-

,arboxylic Acids
disiloxane was precipitated (40%). It forms easily the di-
nitrophenylhydrazone which contains 11.44 % nitrogen, and
thus indicates the presence of two ketone groups in the molecule
of the synthesized compound. The molecular refraction of this
siloxane was found to be 4 units higher than that of E. Warrick
(Ref 6).(A. D. Petrov (Ref 5) found it to be higher by two
units in 4-substituted silanes with one group). The data ob-
tained show that the acylation of benzyldimetbylchlorosilane
is also possible with the anhydrides of the dicarboxylic acids
and the acid chlorides of the monocarboxylic acids without
a noticeable destruction of the compounds taking part in the
reaction under the influence of hydrogen chloride. The pro-
perties of the compounds obtained are given in the table.

ABSTRACTt As the reaction of arylation of alkylhalidesilanes is of extreme
technological importan6e, the authors investigated the arylation
of methyldichlorosilane by benzene, toluol, diphenyl and naphthaleneq
in the presence of boric acid. The interaction of tuluol, diphenyl
and naphthalene with methyldichlorosilanA in the presence of boric
acid resulted in the formation of tolylmethyldichlorosilane,
diphenylmethyldichlorosilane and naphthylmethyldichlorosilane.
Some physical constants, such as boiling points, densities and
ORW-Z~F~ refraction indices, were determined for these synthesized compounds#

ABSTRACT: The present work was done In 19521-1955. The effective-
ness of the fluidized bed application was checked by
the synthesis.of methylehlorosilanes. The reaction
between methyl chloride and silicon was carried out In the
presence of a silicon-copper alloy (20% Cu), at 4-5
atmospheres pressure. The reaction is exothermic and
needs to be cooled. Special apparatus was constructed
which included a cooling syc.tem. Ditnethyldichlorosilane
content was between 42 and 47% In the reaction mix-
ture. A schematic diagram of the apparatus Is given,

ABSTRACT: The compounds, mentioned aboveg though containing other than
triethyl siloxane groups) have been synthesized and described
in various reports (Refs 1-7)- In this report the synthesis
of such compounds having a structure of (C 2H 5)3 Pi 01 iCl2v and
their transformation into cyclic-compounds by means of the oo-
hydrolysis - reaction with dimethyl-dichloro silane, is des-
cribed. The synthesis of the compounds, mentioned last in the
titlep was carried out according to reference 8. There were
ethyl-(triethyloxy)-dichloro silanel mothyl-(triethyl-ailoxy)-
dichloro silane, and phenyl-(triethyl-ailoxy)-dichloro silans.
The structure of these compounds was not only confirmed by
Card 1/2 analytical data, but also by their transformation into acatoxy-

of the newly-produced compounds. The cyclic dimethyl siloxane
containing triethyl siloxane groups were obtained by means of
a co-hydrolysis reaction (see schedule). It was found that in
the co-hydrolysis of methyl-(triethyl siloxy)-dichloro silane
with dimethyl dichloro silanelchiefly tetramer triethyl-ailoly-
hapta-methyl-tatra-siloxane is formed. A co-hydrolysis of the
thyl-(triethyl-ailoxy)-dichloro-silane and phanyl-(triethyl-

chiefly to the formation of trimers (TW92). The cyclic struo-
ture was not only confirmed by analysis but also by the infra-
red spectrum. There are 2 tables and 8 references, 2 of which

Among the syntheses for the production of compounds of type
(R3SiO)nMe), where n denotes the valency of the metal, which
aro known at present, the interaction reaction of the trialkyl
silanolates of sodium and of some other metals is of special
interest (see scheme). These monomers have an Si-O-Me bond and
the aynthesis of polymers which have alternating metal or ox-
ygen atoms in the main chain is directly connected with their
synthesis. By the method, illustrated by the above scheme, the
authors synthesized for the first time the following compounds:
a~ totrakio-(trimethyl-ailoxy)-titanium (Ref 1); b) tetrakis-
- dimethyl-phenyl-ailoxy)-titanium (Ref 3); c) tetrakia-ltri-
ethyl-miloxy) -titanium (Ref 2), and d) tetrakis-(triethyl-ei-
loxy)-tin (Ref 2). In the present paper the above mentioned

Synthesis of Triethyl Siloxy Derivatives of Vanadium SOV/20-126-6--32/67

-method was further developed for the synthesis mentioned (see
schemes). The experiments carried out produced yields of 10-
70% of the theoretically possible yields. The lead-triethyl-
silanolate (Ref 4) showed a considerable reactivity: by the ao-
tion ofI titanium-tetraohloride or of II vanadium oxychloride
on its complex compound the following was formed: I Tetrakis-
-(triethyl-ailoxy titanium or II tris-(triethyl-siloxy)-van&-
date (see schemes~. These reactions which were investigated by
the authors with respect to the titanium-tetra- or vanadium-
-oxychloride, are of general importance for the production of
trialkyl-silyl-derivatives of various elements. The investiga-
tions of the infra-red spectra of some of the compounds synthe-
sized (by N. Gashnikova in the Vaesoyuznyy elektrotekbnicheakiy

TITLE: Synthesis of Some Triethyl Siloxy Alkoxy Titanes
PERIODICAL& Doklady Akademii nauk SSSR, 1959, Vol 127, Nr 5,
pp 1o14 - 1015 (USSR)
ABSTRACTt The compounds mentioned in the title have hitherto remained unin-
vestigated. The trialkyl (aryl) siloxy groups have considerable
hydrolytic stability in the tetrakis-Ctrialkyl(aryl)siloxyltitanes
which is much higher than that of the alkoxy groups bound-t~D
titanium. It is therefore of interest to investigate the proper-
ties of compounds containing simultaneously trialkyl siloxy- and
alkoxy groups. Since the method described by the first author
(Ref 1) is difficultly acoessible the authors investigated the
possibility of the synthesis mentioned in the title by a direct
interaction of triethyl silanol with butyl orthotitanate or pro-
pyl orthotitanates. In contrast to the data from publications
(Ref 3) according to which the reaction between butyl orthotita-
nate and triphenyl silanol is said to lead to a complete sub-
stitution of all butoxy groups by triphenyl siloxy groups the
Card 1/2 authors proved that in the case of the here applied substances,

Synthesis of Some Triethyl Siloxy Alkoxy Titanes SOV/2o-127-5-22/58
in the presence of metallic sodium as catalyst, the reaction
does not only proceed in the direction of the formation of
tetrakis (triethyl~-siloxy) titanium. Also products of differ-
ent degrees of substitution are formed in this connection.
This depends on the ratio of the reaoting components. In the
course of the investigation of the mentioned reaction (see
Scheme) tri-(triethyl-siloxy)-butoxy-titanium (46% of the
theoretically computed value), di(triethyl-siloxy)-dibutoxy
titanium (34%), di-(triethyl-siloxy)-dipropoxy-titanium (21%)
were isolated. Table I shows their physical constants, yields,
and analysis results. Their hydrolytic stability Is being in-
Yestigated. There are 1 table, and 4 references, 2 of which
are Soviet.

ABSTRACT: For the synthesis mentioned in the title, the reaction mentioned
in the subtitle was investigated, the reaction product being
subsequently transformed into bis-(I~-oxy-othox7-mothyl)-tetra-
methyl disiloxane. Although the reaction course described iD,'
scheme (I)-was to be expected, it still proved to be much move
ooimplioated. The two chlorine atoms: the one bound to siliconp
and the one belonging to the chloromethyl group, can both be
easily substituted by a glycol residue. But no A-oxy-ethozq-
mothyl-dimethyl-p-oxy-otholy-silane wav formedi neither was it
formed in the reaction last mentioned in the subtitle (11). In
both cases mentioned ' a relativel low-boiling heterocyclic
derivative was formed (see Scheme~- The substitution of the two
Card 1/3 halogen atoms occurred, in both cases, with 95% at 1000 within 2 h.

Series. L Interaotion of Chloramethyl Di:aothyl Chlorosilane and Bie(chloro-

The formation of the heterocyclic derivative menticned oan
apparently be explained by an intermediate formation of ~_-oxy-
othozy-methyl-dimethyl-t-oxy-ethoxy-silane whinh is then
cyolized to the derivative mentioned, with separation of a
glycol molecule (see Scheme). The intermediate product mentioned,
haNever, could not be isolated. In an interaction of sodi=
.glycolate with bio(ohloromethyl)tetramethyl-disiloxane, -the
formation reaction of the heterocyclic derivative is likely to
proceed in a still more complicated way (see Scheme). Such a
reaction course (via a silanol formationh conditioned by present
humidity traoesp~is also possible in the case of chlowomethyl-
dimetbyl-ohlorosilane. The obtained cyclic product under con-
sideration (boiling point 1380) hydrolizes rather easily to
bie-(P-oxy-othoxy-mothyl)-tetra-mothyl-disiloxane, and polymerizes
while standing under normal conditions with its viscosity and
molecular weight increasing.at the same time. The kinetics of this
polymerization is being investigated at present. Besides, it w4w
proved that the said product can be easily hydrolized by a 1% HCl_
Card 2/3 solution at 600, and is transformed into bis-(&-oxy_ethoxy-zethyl)-

of this polymer group (PTC3 with PMDCS) at the time of gel formation is
lower than that of polymers obtained from cyclic cohydrolysis products.
Hence, the authors conclude that, in the cohydrolysis mentioned, rings
are formed which partly polymerize under the experimental conditions
only on an acid catalyst at increased temperature. On the basis of the
infrared spectra (studies by N. P. Gashnikova), the authors conclude
that during catalytic polymerization the siloxane chains of the polymer
are transformed, and phenyl radicals are partly separated from the
silicon atom at the same time. This leads not only to a ramification of
the polymer molecules but also to a re-grouping of rings. Polymers with
ramified structure have a rather low molecular weight. The thermo-
mechanical properties of polymers as observed by G. Ye. Golubkov are
given. A comparison of the data obtained clearly showed that an inter-
relationship exists between the vitrification temperature and the con-
tent of bifunctional components in polymers. Polymers obtained by
cohydrolysis of PTCS with PMDCS at all quantitative ratios form, from
solutions, brittle films which dry at 200C. Polymers containing di-
methyl siloxane groups form films drying at 200-3000C. The losses in
weight during aging at 350 and 400 OC for up to 10 days are given.

4 moles of dimethyl-dibutoxy silane yielded, with 3 moles of water,

dihydroxydiphenyl propane. The ratio of components was W. 1-n-butoxy-

TEM In continuation of previous published data and investigations, the
authors report on studies of the reaction of trimethyl siloxy trichloro
titanium with butyl alcohol and diphenyl methyl hydroxysilane. In this
connection they found that the reaction of the chlorine substitution by
butoxy- or diphenyl methyl siloxane groups on titanium is accompanied
by byprocesses. The experiments showed that trimethyl siloxy trichloro
titanium and butyl alcohol (in equimolar amounts with 201c butanol excess
and neutralization of the hydrogen chloride by ammonia) react under the
formation of tetrabutoxy titanium. Its formation shows that simultaneously
with the replacement of chlorine by the butoxy group, the trimethyl
siloxy group bound with titanium is also replaced by the butoxy group.

the trimethyl siloxy group in trimethyl siloxy trichloro titanium proved
to be considerable, i.e., not only under the action of butyl alcohol,
but also in the reaction of trimethyl siloxy trichloro titanium with
diphenyl methyl hydroxysilane. Heating of the solution of the last two

TITLE: Production and Properties of Some Organohydroxy Silanes
PERIODICAL: Plasticheskiye massy, 1960, No.,10, pp. 16-19
TEXT: The authors wanted to define the conditions relative to the
production of dimethyl dihydroxy silane and to determine the solubility
of dimethyl dihydroxy silane, diethyl dihydroxy silane, and phenyl
trihydroxy silane in different solvents. Moreover, they wanted to study
their condensation in the presence of HC1. The reactions took place in
vessels rendered water-repellent by means of the FKh(-94 (GK7,h-94)
organosilicon liquid. The synthesis of dihydroxy silanes proceeded from
dimethyl dimethoxy-, dimethyl diethoxy-, and phenyl trimethoxy silane,
respectively, which were obtained by reaction of the corresponding chloro
compounds with the corresponding alcohol in the presence of pyridine.
The following processes are described. 1) 40 9 (CH 3)2 Si(OCH3)2 were
allowed to react at room temperature with 24 g of distilled water, the

solvents (alcohol and water) were distilled off at 3-10 mm Hg, and the
crystals were washed with benzene, heptane, or petroleum ether. Yield
70-75%. 2) 44 9 of (C2 H5)2Si(OC2 H5)2 were allowed to react with 18 g
of 0-5% acetic acid. The liquid turned homogeneous after 5-7 days, and
was then treated as described under 1). 3) 99 g of C6 H5Si(OCH3), were
allowed to react with 50 9 of 0-5~ acetic acid, temperature being kept at
5-100C. The product was cooled down to -200C after 3-5 hours and filtered
off in vacuum. Condensation took place in dioxan in the presence of
0.0012, 0.012, or 0.046 N HC1. The dimethyl compound condensed in O-5N
HC1 to 80-85% within 15 min. The diethyl compound reacted more slowly,
but its condensation rose with an increase of the RC1 concentration, The
same holds for the phenyl compound. Up to a yield of 40% the condensation
proceeded at a constant rate which depended on the concentration of HC1
only. It is believed that dimers are formed at this stage. The gradual
condensation was particularly well observable in the phenyl compound.
Cyolization takes place above the 35% yield. Cyclic and linear polymers
with considerable OR group contents resulted, They were determined by
titration with Fisoher's reagent. The following data for the solubility

TITLE: Thermooxidative and Hydrolytic Stability of Polymers With

PERIODICALs Plasticheskiye massy, 1960, No. 12, pp. 23 - 29
TEXT: In the present paper, an attempt is made to compare the thermo-
oxidative destruction of some types of organic polymers and of polymers
with inorganic chain molecules, and to study the affect of structure and
chemical composition of polymers with inorganic chain molecules on their
stability. The thermooxidative stability of polymers (in some cases in the
presence of fillers) was determined by the loss of weight at different
temperatures in the air, by the thermoplasticity of polymer films on
metallic bases, and the change in chemica:-. composition. Data were obtained
for organosilicon, organofluorine compounds, polyamides, epoxy resins,
terephthalates, phenol formaldehyde resins, and rubbers. As may be seen
from Table 1 and also from Fig. 1, the loss of weight of organic polymers
is much higher than that of polymers with inorganic chain molecules. The

autooxidative reactions proceed very intensely in organic polymers, not
only in the side groups but also in the principal chain. Polymers with
inorganic chain molecules contain carbon which forms qxygen-containing
high-volatility compounds in the side groups only. From among the organic
polymers studied in this paper, only polytetrafluoro ethylene showed
exceptional thermooxidative stability which is explained by the strong
screening effect of the fluorine atom surrounding the principal carbon
chain of the molecule, and by the dense packinU of chain molecules.
Substitution of one chlorine atom for one fluorine atom effects a consider-
able reduction of thermooxidative stability. Similar results are obtained
when studying the thermoelasticity of films (Table 3). All films of organic
polymers exhibited a much more rapid loss of elasticity on heating than the
films of polymers with inorganic principal chains. Fig. 2 shows the heating
time at different temperatures at which polymer films attain an elongation
of less than 4 %. The effect of organic groups and of the structure of
chain molecules in polymers with inorganic chain molecules on the loss of
weight is Illustrated in Table 4. Table 5 gives the half-life period of
decomposition of organic groups on heating, which strongly differs for

individual polymers. The change in thermooxidative stability of polymers
with inorganic chain molecules in the presence of two elements (Ti or Al
and Si) in addition to oxygen in the principal chain is shown in Tables 6
and 7. It may be seen from these tables that the losses of weight in 'Chis
case are lower than in other polymers, but the thermal elasticity of Dol-
ymers which contain aluminum drops most rapidly. The'hydrolytic stability
of polymers was studied on compounds of the genoral composition (R 2sio) xM
(where M denotes aluminum, titanium, tin), on a polytitano-phenyl siloxane,
and a polyalumino-phenyl Filoxane, The rate of hydrolysis depends on the
nature of the metal In the molecul-,,. When studying the stability of poly-

TEXT: In the present paper, the authors report on the condensatioji of
4,4'-dihydroxydipbenylpropane with phthalic acid, isophthalic acid, and
the dimethyl ester of terephthalic acid. The reaction develops in
nitrogen at 2500C and forms, with phthalic acid, a polymer having a
melting point of 1050C and, with isophthalic acid, a polymer with a
melting point of 2600C. As terephthalic acid sublimates at high
temperatures, the reaction was carried out with its dimethyl ester in
the presence of lead oxide at 3000C. The resulting polymer had a melting
point of 2800C. As shown by the Pig., the viscosity during the
polymerization increases first rises slowly and then with increasing

Copolymerization began at 1300C with the liberation of ethanol (Table 2),
and was finished at 1900C. The copolymer obtained had good mechanical,
thermal, and dielectric properties. As mentioned in Table 3, its
hardness is somewhat less than that of polyethyleneterephthalate, but
greater than that of polyorganosiloxanes. A Fig. shows that the loss in
weight due to aging at 2500C is less than in the case of polyethylene-
terephthalate, and approaches that of polyorganosiloxane films. The
breakdown voltage in dry films amounted to 120-140 kv/mm at 1200C. There

trifunctional, and bi- and trifunational monomers. The reaction time of
the poly organo siloxane polymerization in dependence on the amount of the

rules governing the above polymerization. Polymers produced by cohydro-
lysis of methylchloro silane and phenyl trichloro silane, methyl tri-
acetoxy silanep and phenyl acetoxy silane (polymer !-A) were used for
this investigation. Polyaluminum siloxane A-16 (Ref. 1) was used as
catalyst. Table I gives the characteristics of the polymers used* Fig. 1

added polymer A-16. Already with 0.5% of the polymer A-16, a considerable
reduction of the polymerization time was found. Fig. 2 shows the dependence
of the polymerization time of a 99% mixture of I- X (I-Kh) and 1% of A-16
on the amount of dimethyl aniline and pyridine, respectively. The amount
of the tertiary amine addition also reduces the polymerization time of the
polymers 1-Kh and I-A (Figs- 4,5)- For the evaluation of the maxima of the
curves shown in Figs. 2 and 3, the molar ratio between tertiary amine and
aluminum in the mixtures inve6tigat6d,'wds calculated for points cor-
responding to the maximum value of the polymerization time (Table 2). The
maxif'num polymerization time in all cases approximately corresponds to the
equimolar ratio between the amount of the amine addition and the aluminum
in the polymer molecule, The mechanism of the interaction between poly-
aluminum ethyl siloxane and the organosilicon polymer was explained by
the data obtained. Finallyp the syntheses of polymers 1-Kh, 1-A, and A-16
are described. Their elementary composition is given in Table i. The de-_
termination of the polymerization time is also described, respective
results being graphically presented in Figs. 1 to 5. There are 5 figures,

were investigated. Hydrolysis and condensation showed that these compounds
,produce polymers which easily change from the fusible and soluble into
the infusible and insoluble states. The fact that these processes take
place at temperatures below 1000C is explained by the high functionality
of the iniiial monomers which easily develop structurized polymers. In
this paper it was attempted to explain the formation mechanism of such
polymers, First, low-moleoularp crystalline, cyclic compounds with many
hydroxyl groups are developed which are very unstable and easily become

the structure ['-S'(CH3)2_C"2_NH- (CH 2)6_NR_CH2 -3 i(C11 3)20jx , making use Of
the high reactivity of the halogen of the methyl group bound to silicon
with amines. In the present paper, they report on the reaction of bis(chlo-
ro-methyl)-tetramethyl 911oxane with hexamethylene diamine. The reaction
was performed by adding 0.315 moles of siloxane to 0.63 moles of molten
hexamethylene diamine. It proceeded exothermically with a temperature in-
oroase up to 2000C. The low increase in viscosity, however, showed that the
required linear polymers had not f8rmed. Atari equimolecular ratio of com-
ponents, 60% distilled over at 170 C and 1 mm Hg, 25~ could not be distilleL

the siloxane bond in the diketo-.-dicarboxylio acid nor a cleavage of the
Si.-C bond in organosilicon glycol. As is shown in Fig. 1, the acid
number drops during polycondeneation while the ester number rises. The
polyesters obtained are high-viscous, dark-colored substances well solu-

polyesters rises with the number of dimethyl siloxane groups in diketo
dicarboxylic acid. On the reaction of the polyester obtained from diketo
dicarboxylic acid (n-5) with hexamethylene diibocyanate, the authors
obtained an elastic, rubber-like, cresol-soluble product. The change
(increase) in viscosity as dependent on the reaction period is illustrat-

condenses with adipic acid without a cleavage of the Si-C bond to form a

TEXT# The properties of bie(hydroxy-methyl)-tetramethyl-disiloxane were
investigated to find out whether the universal esterification methods may
be applied to this compound. The stability of this compound was investi-
gated by changing the condition 11 of synthesis. Bis(laydroxy-methyl)-tetra-
mothyl-disiloxane was obtained from bio(acetoxy-mothyl)-tetramethyl-
disiloxans by treating it with methanol in the presence of HCl (for
72 hours at 200). The methyl acetate resulting in addition to the former
and the excess of methanol were distilled from the acid reaction mixture
or from the mixture previously neutralized by means of sodium bicarbonate.
The content of hydroxyl groups and Si in the compound remained unchanged
both in the neutralized reaction mixture and ~n the compound distilled
off; both were stable for four months (no change of visoosity~ no water

was esterified with methaorylio acid chloride and allyl formic acid
chloride. The reaction schemes are given. The starting material + allyl
formic acid chloride gave bia(carboxy-allylate-mothyl)-tetramethyl-di-

formic acid chloride + methaorylio acid chloride led to 1-mothaorylate-
mothyl-2-carboxy-&llylate-mothyl-tetramethyl-disiloxane (yields 19%)o The
poor yield is explained by the considerable tendency of the reaction
products t9ward further polymerization. Polymerization wit peroxy
initiators proceeds very smoothly. Solidq vitreous polymeralare formed.

With Acids
PERIODICAL: Zhurnal obshchey khimii, 1960, Vol. 30, No. 7,
pp. 2397 - 2400
TEM The reactions of organosilicon amines with acids have hitherto
been little described (Ref. 1). The authors studied the reaction of
bis(phenylaminomethyl)tetramethyldisiloxane with adipic-, phthalic-,
succinic-, and fumaric acid. At 1500C under normal pressure and in the
vacuum the condensation with adipic acid took place very slowly. This
reaction was also made with the above acids at 250 0 and 300 0 in the
nitrogen current. On heating the above siloxane with adipic acid at
2500 a certain amount of water was separated and on further heating a
product was condensated which did not mix with water. On distillation
considerable amounts of this product were obtained. The reaction
products are a mixture of hexamethyloyclotrisiloxane, octamethylcyclo-

tetraBiloxane, and methylaniline. In this case, only small amounts of
water are separated. The condensation product is a viscous liquid con-
taining 3-5% silicon, or a low-melting resin without silicon (when the
reaction lasts until the volatile products are distilled off). in con-
densing the above siloxane with the other acids, e.g. with terephthalic-,
succinic-, and fumaric acid the process takes place in similar way. The
experimental data obtained show that the reaction between the secondary
amine of bia(phenylaminomethyl)tetramethyldisiloxane and the dibasic
organic acids is very complicated and does not lead to organosilicon
polyamides; in the further course of the reaction the S-C and Si-O-Si
bonds are cleft (Scheme 1). At high temperatures, the water which is
separated in this case reacts with the reaction products, or with
bis(phenylaminomethyl)tetramethyldisiloxane which causes the cleavage of
the 8-0 bond (Scheme 2). Besides octamethyloyclotetrasilaxane also hexa-
methyloyclotrisiloxane is formed whose formation is connected with the
cleavage of the Si-O-Si bond. The mixtures of viscous and solid particles
which cannot be distilled are difficult to separate and probably the
reaction product of methylaniline qw ith the acids. There is 1 non-Soviet
reference.

TEXT: A new polymer, oalled(OK C(FKS , is produced in the USSR
which has previously been described (Ref. 3~. This polymer readily oom-
bines with anorganic fillers, and with 33-35% of filler it gives a material
for sealings working at high temperatures. There are three gradeus FKS-1,
FKS-2, and FKS-3, with 55, 45 and 33% of filler, respectively. Compared
with heat resistant rubber on silico-organio or other base it has higher
mechanical strength, heat resistance, is less affected by kerosene or d'L-
chloroethane, and does not deteriorate without air access. Vulcanization
for 24 hours in 150 and 20000 lowers its tensile strength and raises
the elongation capacity; vulcanization in 250OCincreases the tensile
strength to 60 kg/cm2 at a 280% elongation; vulcanization in 3000C has
negative effect. Short treatment in 35000 without air access in a press
mold under pressure also gives good result and even faster. The behavior

for electroinsulating linings, insulation for electric wires operating in
300 and 3500C over long periods and for short time (10 hours) in 4000C
FKS-2 is frequently used for sealing undetachable joints working at 40;0C

capable of withstanding temperatures of up to 5000C. Some organoalumosiloxanes
dissolve readily in water and are similar in structure to alkite and anorthoolase.
They have good adhesion to glass, metals, asbestos and fabrics and can therefore
be used as hydKophobizers for fabrics, paper, leather and building material. Poly-
organotitanosiloxa.nes are also used as hydrophobizers. Non-friable coatings can
be obtained from a 50/50 mixture of polyorganoborosiloxane and polymethylsiloxane.
The introduction of boric acid, boric ethers or borium anhydride to polydimethyl-
s1loxano rubbers gives them greater resilience to sudden stress. Polymers can
now be synthesized with a basic sil.oxane chain containing periodic inclusions of
nickel, cobalt, chromium or tin atoms. Chemists have developed high-molecular
compounds with inorganic molecule chains framed by organic or organosiloxane
groups. Silicon, aluminum, titanium boron, lead, tin or phosphorus are commonly
used for the main chains. Alukons (polym!ars with chains"of aluminum and oxygen)
are soluble in organic solvents and soften at temperatures ranging from 50 to
