PRODUCTION OF POLYSILANE

PURPOSE: To obtain a polysilane having high molecular weight and narrow molecular weight distribution and useful as a photoconductive material, etc., in high yield by carrying out the polycondensation of a specific dihalosilane in a solvent in the presence of an alkali metal.

Summary:PURPOSE: To obtain a polysilane having high molecular weight and narrow molecular weight distribution and useful as a photoconductive material, etc., in high yield by carrying out the polycondensation of a specific dihalosilane in a solvent in the presence of an alkali metal. CONSTITUTION: This polysilane is produced by the polycondensation reaction of (A) a dihalosilane of formula I or formula II [R1 and R2 are each a 1-22C (substituted)alkyl, a (substituted)alkoxy, a 6-22C (substituted)aryl or a (substituted)aryloxy; R3 is a 1-22C bifunctional organic group; X is Cl, Br or I; a, b and m are each 1-50] in (B) a solvent (e.g. toluene) containing a quaternary ammonium salt of formula III [R. to R7 are each a 1-20C (substituted)alkyl; at least one of R4 to R7 is a 6-20C (substituted)alkyl] using (C) an alkali metal (preferably dispersed in the form of fine particles of e.g. <=0.1mm diameter).
