PURPOSE: A composition having good balance of heat resistance, impact resistance and molding properties, and improved weld strength, obtained by blending a thermoplastic polycarbonate with a graft copolymer containing specific two rubber-like polymers. n CONSTITUTION: (A) 10W70pts.wt. graft copolymer comprising 10W50wt% rubber- like polymer, 30W77wt% aromatic vinyl monomer, and 7W36wt% vinyl cyanide monomer (100wt% total amount), having 10W60% graft effect and 0.4W0.8 reduced viscosity is blended with (B) 10W50pts.wt. graft copolymer comprising 50W70wt% rubber-like polymer, 18W43wt% aromatic vinyl monomer, and 4W20wt% vinyl cyanide monomer (100wt% total amount), having 10W60% graft effect and 0.3W0.6 reduced viscosity of resin component, and (C) 20W80pts. wt. thermoplastic polycarbonate. n COPYRIGHT: (C)1986,JPO&Japio |
