Abstract
A phenylmethylpolysilane polymer is prepared by the addition of a small amount of phenylmethyldichlorosilane to dimethyldichlorosilane and reduction of the resulting mixture. The polymer is a gum or meltable resinous material which has utility as a precursor for preparing silicon carbide fibers.
