Abstract
The invention comprises compounds of the formula <FORM:0980109/C3/1> where n and a are each 0 or 1, and b is 1, 2, or 3, and R is a monovalent hydrocarbon radical without aliphatic unsaturation, and polymers thereof. They are prepared by the reaction of tetraphenyl disiloxane diol-1,3 or hexaphenyl trisiloxane diol-1,5 with the appropriate organohalosilane <FORM:0980109/C3/2> where X is halogen, and a is as above, in an inert solvent, in the presence of a hydrogen halide acceptor, e.g. a tertiary amine, in particular pyridine. Polymers containing the recurrent unit <FORM:0980109/C3/3> where a, b and n, and R are as above, are prepared by heating the compounds (I) alone at 250-350 DEG C., or, preferably, with a catalyst at 120-170 DEG C. A suitable catalyst is a 0.01-1% solution of KOH in octamethylcyclotetrasiloxane, amounting to 10-100 p.p.m. of KOH in the monomer. Copolymers of compounds (I) with themselves or other cyclic polysiloxanes, e.g. those of Specifications 980,101, 980,102, 980,103, 980,104, 980,105, 980,106, 980,107 and 980,108, or cyclic dialkyl- or diaryl-polysiloxanes, are made from mixtures in the same way. All polymers containing units (II) can be cross-linked by irradiation, e.g. with 50,000-20,000,000 eV electrons, and those containing vinyl, cyclo alkyl or adjacent methyl groups, or alkyl groups with more than one carbon atom, can be cured with conventional free radical (e.g. peroxide or zirconyl nitrate) curing agents. Fillers may be added before cure, if desired, and may suitably be silica (aerogel, fumed, precipitated), TiO2, CaCO3, CaSiO3, Fe2O3, Cr2O3, CdS, lithopone, asbestos, talc, carbon black, glass fibres &c. The examples describe the preparation of 1,1 - bis - (m - trifluromethylphenyl)tetraphenyl cyclotrisiloxane and of p-trifluoromethylphenyl pentaphenyl cyclotrisiloxane, and the preparation and use of their polymers for encapsulation of transformers. Also described is the preparation, and cure by irradiation, of a copolymer of octamethylcyclotetrasiloxane with 1-methyl-1 - [3,5 - bis - (trifluoromethyl) - phenyl] - hexaphenylcyclotetrasiloxane. Uses:-Seals in automotive transmissions, flexible supports for elements to be used in atomic reactors.
