ABSTRACT:
A process for producing polycarbosilane partly containing siloxane bonds, ich comprises adding 0.01 to 15% by weight of polyborosiloxane having phenyl groups in at least a part of the side chains of Si with its skeletal structure being composed of B, Si and O to a polysilane having the structure ##STR1## wherein n is at least 3, and R.sub.1 and R.sub.2, independently from each other, represent methyl, ethyl, phenyl or hydrogen; and heating the polymer mixture in an atmosphere inert to the reaction thereby to polymerize it. The polycarbosilane has excellent properties, and is especially suitable as a raw material for the production of silicon carbide fibers.
