POLYCARBOSILANE AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a polycarbosilane in which a phenyl group having a phenolic hydroxy group protected with an organic substituent is bonded to each Si atom in the main chain and to provide a method for producing the same. SOLUTION: The polycarbosilane has repeating units represented by formula [1] (wherein R1, R2, R3, and R4are each a 1-6C monovalent organic group being an aliphatic saturated hydrocarbon group, an alicyclic saturated hydrocarbon group, or a phenyl group; and at least one of R2to R4is a tertiary-carbon- containing aliphatic saturated hydrocarbon group, a 4C or higher alicyclic saturated hydrocarbon group, or a phenyl group). The method comprises polymerizing an organosilicon compound represented by formula [2] (wherein R1, R2, R3, and R4are as defined in formula [1]). COPYRIGHT: (C)2004,JPO
