CARBON-CONTAINING BLACK GLASS FROM HYDROSILYLATION-DERIVED SILOXANES

摘要

Carbon-containing black glass compositions of matter having the empirical formula SiC.sub.x O.sub.y and derived from the precursor polymers obtained by reacting (a) cyclo siloxanes and (b) non-cyclic siloxanes, each of the reactants having either or both of hydrogen and an unsubstituted vinyl group whereby a polymer is formed by a hydrosilylation reaction.
