<p>A flame-retardant polycarbonate resin composition characterized by comprising 100 parts by weight of a polycarbonate resin (A), about 0.01 to 8 parts by weight of a silicone compound (B) whose main chain has a branched structure and whose organic substituents bear aromatic groups, either about 0.03 to 5 parts by weight of a metal salt (C) of an aromatic sulfur compound or about 0.01 to 5 parts by weight of a metal salt (D) of a perfluoroalkanesulfonic acid and, if necessary, about 0.05 to 5 parts by weight of a fiber-forming fluoropolymer (E). This composition is remarkably improved in flame retardance without impairing the impact resistance and moldability, and is out of danger of generating a halogen-containing gas due to a flame retardant in burning by virtue of its being free from a flame retardant comprising a chlorine or bromine compound, thus being advantageous in respect to environmental protection.</p> |
