Polyorganotitanosiloxanes. .1. Synthesis of poly-bis-(acetyl-
acetonate) organotitanosiloxanes
Vysokomolekulyarnyye soyedineniya, v. 3, no. 9,
1321-1325
TEXT: As the formation of polymer6 with linear chains is rendered difficult
owing to the hydrolytic instability of the Ti-O-C bona of the alkoxy
derivatives of orthotitanic acid, the authors tried to use intracomplex
titanium derivatives. The present paper deals with the cohydrolysis of
alkyl-(aryl-) chlorosilanes with bis-(acetylacetonate) dichlorotitanium
(BADT). In the cohydrolysis of dimethyl dichlorosilane (DIIDS), diethyl
dichlorosilane (DEDS), methyl-phenyl dichlorosilane (MPDS), and methyl-
vinyl dichlorosilane (MVDS) with BADT, the yield of polymers with Ti-O-Si
chains is only 35;9 in the absenco of acceptors, sinco 6(Yj,'o BADT does not
react. It hydrolyzes with separation of acetylacetonate groups and forma-

TEXT: The authors synthesized cyclic compounds in which three oxygen
atoms are bound to a silicon atom, and studied their polymerization in the
presence of acid and basic catalysts. For this purpose, they synthesized
bis(hexamethyl-diphenyl-tetracyclosiloxane) oxide (I) and heptamethyl(tri-
methyl-siloxy)cyclotetrasiloxane (II), namely (I) by cohydrolysis of
dimethyl dichloro silane and phanyl trichloro silane by water in acid
medium at 25-300C, 2 hr, and (II) by cohydrolysis of methyl(trimethyl-
siloxy)dichloro silane and dimethyl dichloro silane under the same condi-
tions. The compounds were isolated by fractional distillation, and
identified by their elementary composition, infrared spectra, and molecular
weights. The infrared spectra of (I) showed absorption bands for Si-C 6H5

TEXT: The authors studied synthesis and polymerization of organosiloxanes
containing methyl alkoxy siloxane groups besides dimethyl siloxane groups.
The heptamethyl alkoxy cyclosiloxanes were synthesized by double decomposi-
tion of disodium-1,5-dioxy-hexamethyl trisiloxane (I) and methyl alkoxy
dichloro silanes:

(I) with methyl ethoxy dichloro silane, and heptamethyl butoxy cyclotetra-
siloxane (III) was obtained with methyl butoxy dichloro silane~ The
resulting alkoxy organocyclotetrasiloxanes are transparent liquids; their
properties are given in Table 1. Their structure was determined on the
basis of results of the ultimate analysis, the infrared spectra, and the
quantitative reactions for alkoxy groups, The ring opening of the
heptamethyl alkoxy cyclotetrasiloxanes in the presence of KOH as a
catalyst was dilatometrically studied at '130OC; it was found that the com.-
position of the organosiloxane groups on the eight-membered ring strongly
affected the course of polymerization. When determining the degree of
polymerization from the change in volume of the polymer (Table 2), the
authors found that polymerization was strongly delayed by introducing
alkoxy (mainly butoxy) groups. III polymerizes slowly (Curve 1, Fig, 2)
but with high yield (84.28%) to a polymer with a molecular weight of
2'140 whereas II polymerizes faster (Curve 2. Fig, 2) with a yield of 81.82%
to a polymer with a molecular weight of 2200t The polymerization rfte
drops in the order: octamethyl cyclotetrasiloxane >II >III., An analysis
of polyheptamethyl butoxy cyclotetrasiloxane shows that its composition
corresponds to that of the chain link in the formula.

TEXT: rolar groups bound to Si are introduced to increane the mechanical
stretq:th and the adhesion of polyorganosiloxanes (POS). Since the
stability of' the Si-radical bond is often reduced by such introduction,

recommended. The functional groups contained in the copolymer also permit

TITLE: The hydrolysis of cyclic polymethyl Bilazanes
PERIODICAL: Zhurnal obehchey khimii, v. 31, no. 12, 1961t 4038-

TEXT: The authors investigated the hydrolysis of octamethyl cyclo-
tetrasilazane (A) and hexamethyl cyclotrisilazane (B) in the pre-
sence of acidB, alkalis and NH .4+ - 8alts, in homogeneous and hete-
rogeneous media. Specifically, a mixture consistin of one of the
silazanes (3.65 gr , a solvent (45 ml), and water f5 ml) was boiled
to reflux for up to 48 hours. The evolved NH 3 was trapped in water
and titrated in situ every 30 mins. The tabulated results can be
summarized as follows: Compound A (in toluene) is wholly hydrolyzed
after 48 hours in the presence of KOH (0 5% and 10%). In the pro-
Bence of H01 (0-5 N)q H2SO4 (0.1 N and 0:5 N), and NH 4HS040 the

Si group; next the N +_ Si bond is hydrolyzed and the ring opens,
with a NH2 group on one end of the chain and a silanol group on the
other; the third step consists in the addition of H + to this NH2
group which is converted into NH 3 ; another molecule of water
breaks the N +_ Si bond, giving rise to NH 3 and a silane diol. The
reaction then continues to the ultimate breakdown of the molecule.
Attempts to hydrolyze both compounds-by exposing them to moistened
air failed becaiAse of their high volatility. Therefore, these sub-
stances are iinsuitable for the hydrophobization of paper and build-
ing materials. There are 9 f1gures and 24 references: 4 Soviet-

TITLE: Poly~ondensation as a method of producing polydialkyl
siloxane and polyaluminum dialkyl siloxane elastomers
PERIODICAL: Akademiya nauk SSSR. Doklady, v. 138, no. 2, 1961, 361-362
TEXT: A new method of synthetizing polydialkyl siloxane elastomers having
straight molecular chains is discussed, It is based on the polyoondenea-
tion, of bi-functional oligomers with bi-functional ailiooorganic monomers.
This process takes place in 2 stages: 1) production of oligomers by the
known methods (see diagram no. 1)1 2) polyoondensation or heterofunotional
polycondensation of the monomers produced, whereby elastomers of high
molecular weight are formed. Of the elastomers having inorganic principal
chains and framing organic radicals only polydimethyl siloxane elastomers
including modifications are known. Up to the present, it has not been
possible to produce elastomers by hydrolysis and polycondensation or by
heterofunctional polycondensation of different bi-functional monomers; the
Card 1/6

S/020/61/138/002/020/024
Polyoondensation as a method of producing, B103/B220
side reactions caused the formation of linear as well as cyclic products.
The characteristic of the method described by the authors is based on the
fact that in the two-stage process mentioned the formation of cycles of
low molecular weight in the final stage is impossible. The oligomers
subject to polycondensation have such a degree of polymerization that ring
formation becomes impossible. From elastomers produoed by this method,
types of rubber can be produced by vulcanization, which have properties
analogous to those of standard polydimethyl siloxane rubber. Furthermore,
the authors stated that differently high polycondensated a,O-dihydroxy
polydimethyl siloxanes undergo the following reactions, whereby linear
polymers are formed with atoms of aluminum, titanium, or boron in the in-
organic polymer chain: aluminum butylate gives [(CH 3)2S'012 8[Al (OC4R9)01
with a molecular weight of 30000; tributoxy boron gives
[(CH 3)2S'0135[B (OC4H9) 0], molecular weight 34000; tetrabutoxy titanate
gives L(CH 3)2S'0135 [Ti (OC4H9) 0] .Dependent on the functional end groups
ofthe oligomers, the polycondensation can proceed with formation of
various products of low molecular weight (see diagram no. 2). The

polymers produced by the authors are elastic soluble substances with a
molecular weight of 100000 to 200000. Those having a metal atom in the
chain are highly reactive due to the retaining of the functional group,
at the metal atom. The rubber materials, thus obtained, are similar to
those produced from polydimethy! siloxanes, but have still better
properties. a,w-dichloro polydimethyl siloxanes were prodUCFd by the
abovementioned methodsi K, A. Andrianov, V. V. Severnyy, B. G. Zavin

Therefrom, oligomere were produced with siloxane chains of various lengths
from which a,45-dihydro polydimethyl siloxanes were obtained by hydrolysis.
These siloxanes were produced equally from dimethyl diaoetoxy siloxane.
Mention is made of white soot Y-333 40 (U-333 40) and of the method of
determining the molecular weights by Terentlyev, which is however, not
explained in detail. The polymer UC 6H5)(CH3)SiOAl (0C 4H;) Oln was

explained only ty reactions (3) and (4), and not by pyrotysis of cliloro-
benzene in a reducing medium. In special experiments conducted on this
pyrolysis, the authors found that the benzene yield did not exceed 9%
(in hydrogen medium) and 2.2 % (in silane medium).. On the other hand, in
the production of phenyl dichloro silane 55 - 60 % benzene formed~ Also
the small yield of highly boiling products in the production of phenyl
dichloro silane points to the unimportant part played by pyrolysis. S. A.

TEXT: The effect of catalytic amounts of iron chloride on the reaction of

with 173 by weight of iron chloride, and without-any, were conducted under
equal conditions: sealed glass ampuls, kept at.2500C for 5 hrs, rectifies_
tion of the mixture first at atmospheric pressure, then at 4 mm Hg-
Results: Without iron chloride, only cL,w-dichloro-dimethyl siloxanes
containing 4, 7, and 10 silicon atoms formed. When using iron chloride,
telomerization takes place with the Si-O-Si bonds being ruptured and all

being formed with 2 to 7 silicon atoms. The following mechanism of cleavage
was suggested: The reaction begins by a coordination of the iron atom with
an oxygen atom in the siloxane chain either of the telomer or dimethyl
cyclosiloxane. An active complex forms which then decomposes. The
assumption thet this reaciion takes place in equilibrium was confirmed by
experiments with octamethyl cyclotetrasiloxane and dimethyl-dichloro silane
at different component ratios (Fig. 2; Table 1) and also by the fact that
the composition of the reaction products is determined by the quantitative
ratio of the Si-0- and Si-Cl- bonds in the system, not by the type of
compound used. The reaction examined was suggested as an easy method of
synthesizing low-molecular and high-molecular 1,(j-dichloro-methyl siloxanes.

In the polymer, the-SisTi ratio was always higher than that of the
initial substances. Cohydrolysis of bie(aoetylacetonate)dichloro
titanium with methyl trichloro silane yielded maximum, poly-bis(acetyl-
acetonate)titano phenyl siloxane (I) minimum ratio. The osmometrically
determined molecular weight of I was 103,000. All polymers showed, in
the infrared spectrum, absorption bands for Ti-O in the Ti-O-Si groupt
and complete absorption for Si-O in the Si-O-Si group. Analyses and
investigations of properties of 1, poly-bis acetylacetonate)titano methyl
siloxdne (II), and poly-bia(aoetyla*oetonate~titano ethyl-'siloxane (III)
showed cyclolinear structure with oxygen-bound chains of eight- or six-
membered rings. The viscosity in benzene was 0.073 for 1; 0.069 for II;
0.0670 for III. The yellow, film-forming polymers were structurized at
no, 16o, and 200OC; they became unsoluble except for I which was
partially soluble even 'after 4 hr heating at 2000C. In this case, their
thermomechanical properties correspond to those of structurized polymers.
The structure of II and III is an intermediate stage between crystalline
and amorphous structures, only I is amorphous. The OU gr~oups were
determined according to Terentlyev. The infrared spectra were taken at

reactivity increases with a higher number of silsesquioxane links in the
chain. The:atronger reactivity of silsesquioxane bonds as compared with
siloxane bonds is probably connocted with the fact that the silicon atom
bonded with three oxygen atoms is more electropositive and the attack of I
these bonds gets more effective during thet;aotion of nualeophilio reagenta.

Tz",XT: An attempt was made to polymerize inorganic cycles containing
silicon, oxygen, and phosphorus, and to copolymerize them with octamethyl
cyclotetrasiloxane. Tetramethyl cyclomethyl phosphinoxydisiloxane and
hexamethyl cyclomethyl phosphinoxytrisiloxane were polymerized with H 2s0 41

slight increase in viscosity indicated that polymerization was very poor.
The thermal copolymerization of octamethyl cyclotetrasiloxane with tetra-

TE)Cr; High temperature condensations of methyl dichlorosilane (I) with
methyl chlorophenyl dichlorosilane (II) (reaction 1), methyl phenyl chlo-
rosilane (III) with p-diclilorobenzene (reaction 2) and of III with methyl
chlorophenyl phenyl chlorosilane (IV) (reaction 3) were investigated. Re-
action 1 was carried out with 1:1i molar ratios of the reagents at 570,
600, 620, 640 and 670 0C9 with contact times of 40, 509 60 and 80 sec., in_
stainless steel t-ubes and yielded a mixture of the ortho-, meta.- and par&
isomers of bin (methyl dichlorosilyl) benzene (A). It was found that the
yield of A, under optimum conditions (6400C, 60 see.), was 27%, calculated
with respect to I. The product then consisted of 60% of the liquid meta-
isomer and 40% of the crystalline ortho- and para-isomers. Reaction 2 at
