Patent ID: 8080618

Claim:
A thermoplastic resin composition comprising: about 100 parts by weight of a binary base resin comprising (A) about 10 to about 99 parts by weight of an epoxy group-containing styrenic resin and (B) about 1 to about 90 parts by weight of a polyester resin; wherein said epoxy group-containing styrenic resin (A) comprises about 5 to about 50% by weight of an epoxy group-containing vinyl copolymer resin (A 1 ) and about 50 to about 95% by weight of a rubber modified styrenic copolymer resin (A 2 ); (C) about 0.1 to about 10 parts by weight of a thermoplastic polyester resin, per about 100 parts by weight of the binary base resin; wherein said thermoplastic polyester resin (C) is prepared by polymerization of acid components and diol components, and the diol components comprise a cycloaliphatic diol; (D) about 0.05 to about 2 parts by weight of a hindered phenolic compound, per about 100 parts by weight of the binary base resin; (E) about 0.05 to about 4 parts by weight of a phosphite compound, per about 100 parts by weight of the binary base resin; and (F) about 0.2 to about 6 parts by weight of a compound comprising a HALS compound, benzotriazol based compound, or a combination thereof, per about 100 parts by weight of the binary base resin.
