Abstract
A thermoplastic polyester resin composition having an improved impact resistance is disclosed. This composition is comprised of (A) 30 to 70 weight parts of a polyester resin composed mainly of a polyalkylene terphthalate, (B) 5 to 28 weight parts of a polycarbonate resin, (C) 5 to 35 weight parts of a graft copolymer obtained by graft-polymerizing a monomer selected from aromatic vinyl monomers and methacrylic acid ester monomers in the presence of a rubbery polymer, and (D) 10 to 45 weight parts of a polyphenylene ether resin, which further comprises (E) 2 to 20 weight parts, per 100 weight parts of the resin composition comprising the components (A) through (D), of a copolymer having a main chain of a polyolefin copolymerized with glycidyl methacrylate and a side chain of a styrene polymer, in which the content of glycidyl methacrylate in the polyolefin copolymerized with glycidyl methacrylate is 5 to 30 weight %.
