Patent ID: 7528207

Claim:
A method of producing a polymer, comprising hydrolyzing and condensing a hydrolyzable-group-containing silane monomer (B) with a polycarbosilane (A) obtained by reacting a polycarbosilane (I) with an alcohol or an organic acid in an organic solvent, the polycarbosilane (I) having a weight average molecular weight of 500 or more and obtained by reacting a compound of the following general formula (1) in the presence of at least one of an alkali metal and an alkaline earth metal, R 1 m Y 3-m SiCR 2 n X 3-n (1) wherein R 1 and R 2 individually represent a monovalent organic group or a hydrogen atom, X represents a halogen atom, Y represents a halogen atom or an alkoxy group, and m and n individually represent integers from 0 to 2.
