Claims
- 1. A thermoplastic polyester resin composition comprising 30-70% by weight of a polyester resin (A) comprising a polyalkylene terephthalate in an amount effective to provide heat stability, said polyalkylene terephthalate comprising a polycarbonate resin (D) in an amount of 5-28% by weight based on the weight of said thermoplastic polyester resin composition;
- 5-35% by weight of a graft polymer (B) obtained by graft-polymerizing at least one selected from the group of an aromatic vinyl monomer in the presence of a butadiene homopolymer rubber, and a methacrylate monomer in the presence of a butadiene homopolymer rubber followed by graft-polymerizing an aromatic vinyl monomer;
- 10-45% by weight of a polyphenylene ether resin (C), said resin (C) being a homopolymer or copolymer having repeating units represented by the formula ##STR2## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are selected independently from the group consisting of hydrogen, an alkyl group, halogens, a nitro group, and an amino group; and
- wherein n is a number greater than or equal to 30; and
- wherein the weight % of said polyester resin (A) is greater than that of said polyphenylene ether resin (C) and the weight % of the rubbery polymer in the graft polymer (B) is from 30 to 80% by weight based on the weight of said graft polymer (B).
- 2. The thermoplastic polyester resin composition of claim 1, wherein n is a number greater than or equal to 50.
- 3. The thermoplastic polyester resin composition of claim 1, wherein said graft polymer (B) is present in said polyphenylene ether resin (C).
