(57) [Problem] To provide a flame-retardant thermoplastic resin composition which has an excellent balance of flame retardancy, impact resistance, heat resistance and moldability and can be used in a wide range. (A) Aromatic polycarbonate resin 50 -80 parts by weight, in the presence of the rubbery polymer (B), an aromatic vinyl monomer, a vinyl cyanide monomer and, if necessary, other vinyl monomers copolymerizable therewith. 5 to 40 parts by weight of a rubber reinforced thermoplastic resin obtained by graft polymerization of a monomer component (provided that vinyl cyanide monomer in the monomer component = 0.5 to 10% by weight); 5 to 30 parts by weight of ester [however, (A) + (B) + (C) = 100 parts by weight], and (D) a flame-retardant thermoplastic resin composition containing 0.02 to 3 parts by weight of polytetrafluoroethylene as a main component. |
