POLYCARBONATE THERMOPLASTIC RESIN COMPOSITION HAVING FIRE RETARDANCY

摘要

PURPOSE: A polycarbonate thermoplastic resin composition prepared by using an organic phosphorous compound derived from dicarbonic acid as a fire retardant is provided, which does not generate stress cracks by bleeding during formation and has excellent char forming capacity. CONSTITUTION: The resin composition comprises (A)45 to 99 parts by weight of polycarbonate resin, (B)1 to 50 parts by weight of rubber modified graft copolymer resin, (C)0 to 50 parts by weight of vinyl copolymer resin, (D)0.5 to 30 parts by weight of an organic phosphorous compound derived from dicarbonic acid and (E)0.005 to 5 parts by weight of one or more fire retardants and fire retardant aids selected from the group consisting of an organic ester phosphate compound, a halogen-containing organic compound, a cynurate compound, fluorinated polyolefin resin and metal salts.
