PURPOSE:The titled composition having improved heat resistance, impact resistance, and molding properties, obtained by blending a composition consisting of specific three copolymers, having a specific flow rate, with polycarbonate. CONSTITUTION:(A) 20-65pts.wt. composition having 3-25 melt flow rate obtained by blending (i) 6-55wt% copolymer comprising 90-50wt% (ratio of numbers of molecules), 10-50wt% maleimide and/or N-aromatic maleimide and 0-30wt% copolymrtizable monomer with (ii) 0-33wt% copolymer comprising 90-40wt% aromatic vinyl monomer and 10-60wt% unsaturated nitrile, and (iii) 3-46wt% copolymer obtained by polymerizing 95-25pts.wt. mixture of 40-85wt% aromatic vinyl monomer, 15-45wt% unsaturated nitrile, and 0-30wt% copolymerizable vinyl monomer on the presence of 5-75pts.wt. rubber-like polymer is blended with (B) 80-35pts.wt. polycarbonate. |
