Process for producing shaped silicon carbide article from the same.

摘要

A new polycarbosilastyrene copolymer which comprises recurring carbosilane units of the formula I:
<CHEM>
and recurring silastyrene units of the formula II:
<CHEM>
and having easy shaping and sintering properties, is produced by ultra-violet ray treatment and/or heat treatment of a polysilastyrane material and is useful for producing a shaped sintered silicon carbide article by shaping the polycarbosilastyrene copolymer to a desired form, by applying an ultra-violet ray treatment or heat treatment to the shaped article, and by sintering the resultant cross-linked, non-fusible shaped article at an elevated temperature.
