    摘要: Novel diaralkyldichlorosilanes of the general formula (I)
    (wherein R 1 and R 2 each represent hydrogen or C 1 to C 4 alkyl, R' and R 4 each represent C 1 to C 4 alkyl, p and q are 0 to 3; provided that R 1 and R 2 are not hydrogen when p and q are 0) can be made from dichlorosilane and the corresponding styrene compounds and are useful as monomers for producing polysiloxanes and as intermediates for synthesizing organosilicon compounds.

    摘要: Novel substituted phenethyldichlorosilanes have the general formula
    wherein R is an alkyl group having 3 to 20 carbon atoms or a phenethyl group. Such compounds are produced by reacting a monosubstituted dichlorosilane RHSiCl 2 at a temperature of 30 to 200°C with styrene using a catalytic complex of platinum and a phosphine compound. Hydrolysis and polymerization of the substituted phenethyldichlorosilanes (I) yields polysiloxanes with good heat-resistance and other desirable characteristics.
