PURPOSE:To provide a composition composed of an aromatic polycarbonate resin, an ABS resin, and an acrylic acid ester graft copolymer, and having improved moldability, low-temperature impact resistance and the thickness- dependency of the impact resistance, and balanced heat-resistance, etc. CONSTITUTION:The objective composition can be prepared by compounding (A) 40-80(wt)% aromatic polycarbonate resin with (B) 20-60% mixture of (i) 100-10% conjugated diene rubber-aromatic vinyl compound-vinyl cyanide graft copolymer and (ii) 0-90% aromatic vinyl compound-vinyl cyanide copoly mer (preferably having an aromatic vinyl content of 55-85%)s, and (C) 1-15% acrylic acid ester graft copolymer. The graft copolymer in the component B is preferably the one composed of 5-70% conjugated diene rubber and 95-30% graft-polymerization compound (having an aromatic vinyl content of 50-80%). |
