PURPOSE:To obtain the titled composition of high impact resistance at low temperatures, good fluidity in molding operation and high releasability, capable of giving molded articles of good appearance, by incorporating a specific (partial) ester in composite rubbery polymer-blended aromatic polycarbonate resin. CONSTITUTION:The objective composition can be obtained by incorporating 100pts.wt. of a resin composition comprising (A) 70-98 (pref. 80-98) wt% of an aromatic polycarbonate resin and (B) 2-30 (pref. 2-20) wt% of composite rubbery polymer selected from MBS resin (pref. containing 30-70wt% of butadiene polymer), MAS resin (pref. containing 5-40wt% of rubber component) and acrylic ester graft copolymer with (C) 0.01-2 (pref. 0.1-1) pts.wt. of an (partial) ester from 12-30C saturated aliphatic monovalent carboxylic acid and 1-30C saturated aliphatic mono- or polyhydric alcohol. |
