Abstract
A thermoplastic resin composition having 100 parts by weight of a resin mixture of (A) from 20 to 98% by weight of a polycarbonate resin and (B) from 2 to 80% by weight of a styrenic resin; from 0.1 to 20 parts by weight of (C) an epoxy-modified block copolymer; and from 0.5 to 20 parts by weight of (D) a grafted core/shell rubber elastomer, can be used in moldings which have a good surface layer peeling resistance and a good impact resistance. Further, a flame-retardant polycarbonate resin composition having 100 parts by weight of a resin or resin mixture of (A) from 20 to 100% by weight of a polycarbonate resin and (B) from 0 to 80% by weight of a styrenic resin; from 1 to 30 parts by weight of (E) a flame retardant of an organic phosphorus compound; and from 0.1 to 10 parts by weight of (D) an epoxy group-containing compound, exhibits good flame retardancy, and its injection moldings have good impact strength and yellowing resistance even in high-temperature and high-humidity conditions and can be recycled.
