Abstract:

Polysilahydrocarbon precursors for silicon carbide ceramic compositions have been prepared by potassium dechlorination reactions of mixtures of chlorosilanes and hydrocarbon olefins such as styrene or isoprene. the presence of branched silyl units in the polymer backbones is critical in providing significant ceramic yields.
