Abstract
This invention is a flame resistant polycarbonate resin composition characterized by blending 0.01-2 weight parts of a silicone compound (B)) wherein a main chain has a branch structure and having an aromatic group in an organic substituent, 0.01-2 weight parts of an alkali metal salt of an aromatic sulfonic acid (C) represented by the following general formula 1 (hereafter, referred to as general formula 1), and 0.05-5 weight parts of a fiber-forming fluorine-containing polymer (D), relative to 100 parts of a polycarbonate resin (A): General formula 1: Am—R—(SO3M)n (wherein, R is a phenyl group, naphthyl group, or a phenyl group or naphthyl group substituted by A, where A is at least one type of substituent chosen from a group comprising a halogen atom, alkyl group, aryl group, vinyl group, alkoxy group, amino group, methyl ester group and ethyl ester group, and M is an alkali metal. Also, when R is phenyl, m and n are respectively the integers 0-5 and 1-2 (m+n≦6), and when R is naphthyl, m and n are respectively the integers 0-7 and 1-2 (m+n≦8). The polycarbonate resin composition of this invention possesses superior flame resistance without losing shock resista…
