Thermoplastic resin composition

Abstract

PURPOSE: To prepare a composition having excellent weld strength, by mixing a polycarbonate resin having a specific reduced viscosity with an ABS resin having a specific melt viscosity characteristic. CONSTITUTION: The objective resin composition is prepared by compounding (A) 20W80pts.wt. of a polycarbonate resin having a reduced viscosity of 0.40W0.55 in chloroform with (B) 80W20pts.wt. of an ABS resin composed of 100W10wt% of an aromatic vinyl compound-diene rubber-vinyl cyanide and/or unsaturated carboxylic acid alkyl ester graft copolymer and 0W90wt% of an aromatic vinyl compound-vinyl cyanide and/or unsaturated carboxylic acid alkyl ester copolymer, and having an apparent melt viscosity of 5×10 3 W1×10 5 poise at a shear rate of 10 2 sec -1 and 1.5×10 3 W1×10 4 poise at a shear rate of 10 3 sec -1 at 250°C. The reduced viscosity of the polymer of the component B in dimethylformamide is preferably 0.50W1.10. COPYRIGHT: (C)1984,JPO&Japio
