PURPOSE:To provide the title compsn. having excellent impact resistance, weld strength and moldability, by adding two specific components to a compsn. consisting of an ABS resin and an arom. polycarbonate resin. CONSTITUTION:10-90wt.% ABS resin (a) obtd. from diene rubber, a vinyl cyanide monomer, an arom. vinyl monomer and optionally, other copolymerizable monomer, is blended with 90-10wt.% arom. polycarbonate resin (b) to obtain a compsn. 1-20pts.wt. polymethacrylate resin (c) and/or polyglutarimide (c) which is a polymer having a cyclic imide unit of formula [wherein R1, R2 and R3 are each H, a 1-20C (substd.) alkyl or aryl] and 0.5-20 pts.wt. MBS resin (d) obtd. by grafting an alkyl unsaturated carboxylate and an arom. vinyl monomer onto diene rubber and/or acrylate graft copolymer (d) obtd. by grafting a vinyl compd. onto a copolymer obtd. from an alkyl acrylate and a polyfunctional polymerizable monomer having a conjugated diene type double bond, are added to 100pts.wt. said composition. |
