Abstract: The invention provides a thermoplastic resin composition characterized by both a polycarbonate resin and a styrenic resin, of which the moldings are not troubled by surface layer peeling and have good impact resistance. Even when a flame retardant is added thereto, the moldability of the composition is still good, and the moldings of the composition still have good impact resistance and aging resistance, and are recyclable. The invention also provides a non-halogen, flame-retardant polycarbonate resin composition having good flame retardancy, and its injection moldings having good impact strength and yellowing resistance even in high-temperature and high-humidity conditions and having good recyclability. The thermoplastic resin composition comprises 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 rubber-like elastomer component of a core/shell-type, grafted rubber-like elastomer. The flame-retardant polycarbonate resin composition comprises 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.
