- 1 - Abstract: The invention provides a thermoplastic resin com- position having good impact resistance, moldability and falling ball impact strength at a weld part. The composition comprises (A) a polycarbonate resin having a reduced viscosity at 25°C in chloroform of 0.40 to 0.55 and (B) an ABS resin comprising 10 to 100 % by weight of a graft polymer of a diene rubber with an aromatic vinyl compound and at least one of a vinyl cyanide and an alkyl unsaturated carboxylate grafted thereon and 90 to 0 % by weight of a copolymer of an aromatic vinyl compound with at least one of a vinyl cyanide and an alkyl unsaturated carboxylate and having apparent melt viscosities at 250°C of 5 x 103 to 1 x 105 poise at a shear rate of 102 sec-1 and of 1.5 x 103 to 1 x 104 poise at a shear rate of 103 sec-1; the weight proportion of the components (A) and (B) being from 20 : 80 to 80 : 20.
