Abstract: The invention comprises carbonyl-containing silanes and siloxanes of formula (I) and copolymers and homopolymers derived therefrom. The homopolymers consist essentially of units of the formula (II) and the copolymers consist of 0.01 to 99.99 mole per cent of units of Formula (II) combined with 99.99 to 0.01 mole per cent of units of formula In the above formulae R is a monovalent halogenated or unhalogenated hydrocarbon radical or a cyanoalkyl radical, R1 is a divalent halogenated or unhalogenated hydrocarbon radical, A is hydrogen, an R radical, a halogen atom or an alkoxy radical, Z is an arylene radical, a divalent aryl ether radical of the type -Ar-O-Q-where Ar is an arylene radical and Q is a hydrocarbon radical, a divalent five-membered heterocyclic aromatic radical having a Group VIa element as the hetero atom, or a substituted derivative thereof, Y is or an alkylene radical, a is 0 or 1, b is 2 or 3, c is 0, 1 or 2 and d is 1, 2 or 3. The compounds of Formula (I) are prepared by acylating an aryl nucleus, including the above defined heterocycles, with a silyl acid halide of formula where X is a halogen atom. If these monoacylated compounds contain a methylene group alpha to the aryl nucleus, they may be converted to the diacylated compounds by oxidation of the methylene group. Alternatively the diacylated compound may be prepared by reducing the carbonyl group of a monoacylated compound to a methylene group with a metal hydride e.g. LiACH4 in the presence of aluminium diboride, acylating the product to produce a carbonyl group attached to the aryl nucleus and then oxidizing the methylene group back to a carbonyl group. Polymers and copolymers may be prepared by hydrolysing these compounds or cohydrolysing them with an organo halo silane. Examples describe the preparation of p(trimethysilylethyl) trimethylsilylbutyrylbenzene, a homopolymer of the formula a copolymer comprising about 5 mole per cent of units derived from this combined with about 95 mole per cent of dimethylsiloxy units, and a vulcanizing composition prepared by mixing the homopolymer of Example 2, ethyl polysilicate and dibutyl tin dilaurate.
