A process for preparing a poly(silvinylene) represented by the following general formula [III]: ##STR1## characterized in that (A) a polysilane represented by the following general formula [I]: ##STR2## and (B) an acetylene represented by the following general formula [II]: R.sup.5 --C.ident.C--R.sup.6 tm [II] are reacted in the presence of a catalyst comprising an isocyanide compound and a palladium compound. This poly(silvinylene) is useful as a photosensitive material and a crosslinking agent. This poly(silvinylene) is obtained generally in high yield irrespective of the type of the substituent possessed by the silane that is a raw material.
