Title Me mechanism of the formation of trifunctional polyphenylailoxanes
Periodical tjzv. AN SSSR, Otd. khim. niuk 6, 1033-1037, Nov-Dee 1954
Abstract MKperiments were conducted with phenyltrichlorosi3ane to determine the
structure of three-functional polymers forming during hydrolysi6 in strong
and weak acid media. It was established that the hydrolysis of trifunctional
monopers in an aqubous medium in the presence of mineral acids results in'
the formation of complex cyclic polymeric products which, when heated slowly
(with certain difficulties), convert into steric polymers.

The properties of dielectrics (particularly those used as insulating
materials) are reviewed mainly on the basis of USSR publications (out of
nine references listed in the bibliography, eight are USSR and 1 W
In the introduction to the article, the principal requirements with which
high polymers used as dielectrics must comply are reviewed. The dielec-
.tric properties,, heat stability,, stability to the effects of sparks or of
an electric are discharge, sensitivity to moisture, mechanical propertiesi.
stability at low temperatures, heat conductivity, and chemical stability
are considered from this standpoint. In connection with the discussion of
beat stability, GOST standards pertaining to this characteristic are listed
&Ud the statement is made that small electrical machines of light weight
and electrical equipment that operates at elevated temperatures require
insulating materials which can stand heating to 180-2000 and occasionally
eve.n up to 2500. As far as stability at low temperatures is concerned,
the author points out that insulating materials may be subjected to tem-
peratures reaching miuus 609 dwing the operation of electrical equipment.

Polyethylene polystyrene# polytetrafluoroethylene (fluoroplasit),, and
aniline-formaldehyde resins are listed as dielectrics suitable for use in
high-frequency equipmenti their properties are described, The high heat
stability (up to 180-20CP) of polytetrafluorethylene and its stability at
lov temperatures (down to minus 730) are mentioned as particularly advan-
tageous characteristics. As dielectrics suitable for use in low-frequency
equipment polyvinylehloride, polyvinylacetals, polyamides (Capron), glyptal
polyesters, phenol-formaldehyde resins, urea-formaldehyde resins, melamine-
formaldehyde resins, and cellulose esters and ethers are listed and dis-
cussed. Organosilicon resins are described in great detail from the stand-
Point of their characteristics as dielectrics. Their superior heat stability
is-emphasized. The article ends with the following passage:
"The increasing demands put to high polymers by the electrical industry
impose continuation of work on the development of new, more effective plas-
tics, an well as on the improvement of already available plastics and the
reduction or their cost.

"'Llne: Vor i Vh i-c- hI -do le: 066~IA ~e- iiwd Primarily it the 8YA
thisis of high polymers with the following propertlest
"1. High effectiveness as dielectrics; which is not impaired at
elevated temperatures (up to 2500 and above that) and high frequencies
.-or reduced as a result of exposure to high humidity or water.
"2. Very low shrinkage on hardening, a property which is essentiaj'.~.-.

"3. High mechanical strength and superior heat stability., for appA

Title Thermooxidative decomposition of organopolysiloxanes
Periodical Khim- prom. No 6, 329-335, Sep 1955
Abstract On the basis of the experiments described, found that linear organ-
opolysiloxanes are decomposed under scission of Si-C and Si-O bonds,
whereas only Si-C bonds are broken in three-dimensional organopoly-
siloxanes. Propose a mechanism for the themooxidative decomposi-
tion of compounds of this type. Determined the half-life of organ-
opolysiloxanes at different temperatures and investigated the de-
pendence between the stability of organopolysi.loxanes, their struc-
ture, and the nature of the organic radicals entering into their
composition. Ten graphs, 5 tables. Six references; one USSR,
since 1940.

and it is shown that the bond in question splits much easier in nonaothyl-
alumoxytrisiloxane and kaolin than In polyalumoxytetra (dimethylphenyldisil-

but at -490), which was connected with partial crystal-
lization. This phenomenon was not discovered in case
of III, and in case of II a similar region was 5 - 70

ABSMACT: During the synthesis of high molecular silico-organic compounds~
it is of great importance to know the hydrolysis reaction of
alkylchlorosilanes or compounds similar to these silanes.
Monomeric silico-organic compounds having more than one hydroxyl
group in the Si-atom cannot be handled properly because of their
low stability. The ability to form polymers by hydroxyl-containing
silico-organic compounds decreases with the increase in molecular
weight of the organic radical connected with the Si-atom and it
is therefore anticipated that alkyltrioxysilanes having an organic
radical of greater molecular weigbt will be sufficiently stable
for separation. In order to prove this point, the authors
investigated the hydrolysis reaction of dichlorophenyltriace-
toxyailane and found that the hydrolysis with a water surplus

ABSTRACT: Report describes ~.he method employed in the synthesis and separation of
ethylsiloxane polymers of linear structure with 3 to 5 Si atoms in the
molecule. The catalytic regrouping method in the presence, of aluminum
silicate was used in the derivation of ethylpolysiloxanes of linear
structure. Hoxnethyloyclotrisiloxane, octaethylcyclotetrasiloxane and
hexaethyldisiloxane, were used as the basic substances for the synthesis.
The separntion of the individual polymers from the hydrolysis products
was accomplished by fractionation in a rectification tower with an Offee-
tiveneas of 20 theoretical plates. During the fractionation of hexaethyl-
disiloxane, the rate of flow of the liquid was 200-250 mlAr and the
reflux number was 10-15. Rectification of the cyclic polymers was con-

ABSTRACT: It is important to produce heat resisting explosion proof
dry transformers for the coal industry because they can be
installed much nearer the coal face than can flame-proof
oil-filled transformers. For the manufacture of such
transformers it is important to have insulating cylinders
and tubes capable of operating at high temperatures and
voltages. This article describes briefly experimental
data on the production and study of heat-stable glass-
fabric cylinders and tubes based on silicone resins.
Polyphenyl-metbyl,-siloxane resin of high thermal &nd water
resistance and i3atisfactory binding properties for glass
cloth was mamfactured on a semi-industrial scale'. This
Card resin was introduced into production at the Kuskovsk Chem-

ABSTRAM On the strength of the investigations carried out the following may
be said: i.) The introduction of the chlorine atom into silicon-
organic polymers of the I.n-hexametbylpolyohlorophenylethylailox&-
nes series and an inorease of the number of terms with ohlorophenyl
groups in the moleoule increases the temperature of glass foxmation,
the dieleotrioity constant, the activation energy of the viscous
flow, ana the conauotometrica-Ily determinea activation energy.
2.) The introduction into the l.n-hexamethylpolych-lomphanylethyl-
siloxane molecule of dimethylsiloxane tems instead of the chloro-
phenyl groups leads to a decrease of the intermolecular forces of
interaction in comparison with molecules of the same silicon atom
number, but with ohlorophenyl radicals. 3-) Dipole moments of
l.n-hexamethylpolyohlor-ophenylethylsiloxanes inorea3e with molecule-
chain grwoth. The introduction of 2 chlorine atoms into the phenyl

xane and polyphenylsiloxane resins, is under investigation. It will
be shown that the above ccmpounds react with the metalt5 under anhydrous
conditions with the formation of metal-siloxane (metal-oxygen-silicon)
linkages.

X- The reactivity of the siltinols is dependent on the stability of their
hydroxyl groups. Compounds which easily undergo condensation do nut react
with metals. Compounds which have stable hydroxyl groups react easily
with metals.
3. It will be shown that by the action of aluminumchloride on the
sodium salts of phenyl- and ethylsilanetriols and of 1,3,5-trimetkyl-1,3,
5-triphenyltrisiloxane, polymers are formed- the Dolyorganoaluminosiloxanes.

ABSTRACT: The destruction of the above-mentioned polymers by thermo-
oxidation is investigated by the application of hydrolysis
products from di- and trifunctional compounds, i.eo no li-
near ones which as it is known are more liable to a destruc-
tion by a heat influence. 2 investigation methods were used,
i. e. the determination of the temperature influence on the
elasticity of varnished samples and the loss of weight during
the aging process. The investigations showed that e.g. the
thermal resistance of the above-mentioned insulating paint is
to a great extent reduced by an addition of oiccatives, that
Card 1/3 is to sayq proportionally to the activity of the catalyst.

The Influence of Pigments
Polymethylphonylsilcxane
This phenomenon is based on structure changes during the
drying process. The influence of a zinc- or lead naphthenate
resp. on the reduction of the thermal resistance which was
not considerable at 2500C increased to a great ext8nt the
loss of weight of the investigation samples at 400 C, lead
naphthenate being the more effective. By means of chemical
analyses of the investigation samples it was found that the
destruction took place in the Si-C binding as well as in the
Si-O binding, whereon, however, a dependence on the type of
the catalyst was observed. Salts of metals with stable va-
lence (e. g. Zn-naphthenate) support the destruction of the
Si-O binding, whereas alternating valence - metal salts
(e. g. Pb-naphthenate) destroy the siloxane binding and ca-
talyse an oxidation of the radicals. Investigations at a
polymethylphenylsiloxane varnish showed that an addition of
pigment reduces its thermal resistance, that is to say, con-
siderably up to 10 ~, then less, the chemical composition of
the pigment playing an important part. Hence it is concluded
that a maximum of 20 - 30 % of pigment is to be added, where-
on for instance titanium oxide is better suited since it is

more abundaBt than lithopone. Experiments were carried out at
250 and 400 C in order to explain the mechanism of tempera-
ture aging of pigwented samples. Here was found that chrome
yellow had at 400 C the greatest destructive effect. Com-
prisingly it is said that the pigments and fillers reduce
the thermoplasticity of polymethylphenylailoxane, whereas
the thermostability of the polyester-modified polymethylphenyl-
siloxanes increase by the pigmentation, whereby a greater
portion of pigments reduceB the destruction by thermooxida-
tion and increases the thermal resistance at higher tempera-
tures, There are 8 figures, 4 tablesq and 5 references, 2

ABSTRACT: In recent time '.'a amino3ilanes gained an constantly in-
creasing practic;al iinpo_-.an-,-9 as active hydrophobizin6 pro-
ducts. However, only few is mentioned in literature about
the chemical proporties of these compounds. In the present
paper some reactions (with the 3-incor, atoLa of the amino
Group) were invev4tigated by means of the example of tri-
ctbylsilane and its netIV,,I- and ethyl-derivatives. Tri-
ethylaminosilane easily reacts with hydrochloric- and hjdro-
bromic acid. The authors obtained derivatives of the tri-
el,hylam--nosilane as well cs derivatives of methyl which have
not yet been described in liter--ture by the interaction of
triethyleliloroeilane with am-monia (or ne corresponding
amine). Table 1 shows the physical properties of the synthet-
ic compounds. In the investigation of these properties it
turned out that the have sufficient thermal stability. Tri-

triethy2chlorosilane (at room temperiture). The reaction
can be a little accelerated at boiline temperature. Table 2
shows the properties of the (by triethylethoxysilane) ob-
tainod compounds. Furthermore the authors found properties of
new conpounds, e.g. of triotlVl-n-propoxysilane, triethyliso-
propoxysilane, trieth~rl-n-butoxysilane, triethylisobutoxyail-
ane, triethylisoamiloxysilane -,%s vell as of triethyl-n-
-octilox,vsilane. Etkyl- and metlVl- derivatives of triethyl-
aminosilane react with alcohols in a sir.iilar manner, Here
the number and the size of the radicals in the nitrogen
atom exercise their influence on the reaction process. Tri-
ethy1dicti-*,laminosillane enters reaction with alcohols, how-
ever, with a considerably lowi~r activity than triethjlUmino-
Gilanc, its nictlql-dorivativeo or trio thylaminooi lanc. Thera

duced, i.e. to the extent to which silicon enters into re-
action (formation of etIVIchlorosilRnes). It was found that
for alloys with a low content of copper (5-9A) the lines of
the general activity in the reaction of the formation of di-
ethylchlorosilane run over 2 maxima. In alloys with a high
copper-content (rv25'1'j) the pzesenoo of only one selective
maximum and cne ziaxi;.Ium of the general activity was determin-
ed. It is assumed that the interaction of ethyl chloride with

on with free silicon in the presence of the separated
copper as catalyst. On the basis of this hypothesis the
variability for alloys with a diverse content of copper can
be explained. During the reaction carbon is to a oonsider-
able extent deposited at the surface of copper which may also
contribute to a decrease in the activity of the mass. There
are 2 figurea, 7 tables, and 5 Slavic references.

ABSTRACT: In this paper a survey is given of the hiCh-molecular
synthetic compounds used as dialectrics in the USSR. Of
the isotactic polymers isotactic polyethylene, polypro-
pylene, polybutene, and polystyrene are produced syntheti-
cally at present,. In contrast to the polymers of the same
class which, however, were produced by the normal way, they
have a much higher melting point and do not dissolve in
most of the solvente.The isotactic polymers make possible
to extend considerably the range of application of the poly-
meric hydrocarbons for electric insulation purposes. Because
of their higher melting point they can be applied as plastics?
as c-ible coverop and as fibers at working temperatures up

do not adsorb humidity at all, Of the heat resistant poly-
mers polytetrafluorethylene is the most interesting. It
permits working temperatures up to 250 0 and 2800C. Of the
polyester resins the types KfVC-l and KrTAC-2 are produced
as dielectrics. It can be seen from the table of the VEI
given here, that these polymers have high electric resistance
and a high volume resistance., Their dielectric characte-
ristics hardly change in moist atmosphere. The polyester
on the basis of terephtalic acid and ethylene glycol known
as Lavsan, Maylar, Terylene are very important for electric
insulation purposes. This polymer produced at the INEOS of
the AS USSR hr,3 a rather straight chain,' it crystallizes
and forms a solid fiber and mechanically solid films. At
the VEI the polyester 124.and a varnish modified by admixtures
(connecting the linear molecules) was developed. From this
varnish enameled lines for a permanent working temperature
Card 2/4 of 130'C were produced for machines of the insulation class B.
