PROBLEM TO BE SOLVED: To provide a polycarbonate/ABS resin alloy which is excellent in flame retardancy, impact resistance and appearance and also excellent in impact strength during high temperature molding.SOLUTION: There is provided a thermoplastic resin composition which comprises: 5 to 20 pts.mass of an ABS resin (B) composed of 60 to 90 mass% of a polycarbonate resin (A), 40 to 80 mass% of an aromatic vinyl monomer component (b1), 20 to 30 mass% of a vinyl cyanide monomer component (b2), 10 to 30 mass% of a diene rubber polymer component (b3) and 0 to 30 mass% of the other monomer components; 0.01 to 1 pt.mass of a fluoropolymer (D); 1 to 3.5 pts.mass of a graft copolymer (E) obtained by graft polymerization of an aromatic vinyl compound and/or a (meth)acrylic acid ester compound to a diene rubber; and 0.5 to 3 pts.mass of talc (F) having an average particle diameter of 5 to 15 μm based on 100 pts.mass of a base resin composed of 0 to 30 mass% of a phosphoric ester compound (C) represented by the formula (1). In the ABS resin (B), the diene rubber polymer component (b3) has a number average particle diameter of 100 to 350 nm and the graft copolymer (E) has a number average particle diameter of 100 to 350 nm. |
