FLAME-RETARDANT POLYCARBONATE RESIN COMPOSITION

摘要

A flame-retardant polycarbonate resin composition characterized by comprising (A) 100 parts by weight of a polycarbonate resin, (B) 0.01 to 8 parts by weight of a silicone compound in which the main chain has a branched structure and which contains organic substituents comprising aromatic groups, and (C) 0.01 to 2 parts by weight of an alkali metal salt of a specific aromatic sulfonic acid and optionally further containing (D) 0.05 to 5 parts by weight of a fluoropolymer capable of forming fibers. The composition has high flame retardancy while retaining intact impact resistance and moldability. Since the composition contains no halogenated flame retardants comprising a chlorine or boron compound or the like, it has no fear of generating, upon burning, a halogen-containing gas attributable to such a flame retardant. Thus, it has an excellent performance also from the standpoint of environmental protection.
