Thermoplastic blend compositions comprise polyphenylene ethers blended with modified polyesters. The modified polyesters comprise linear polyesters, such as polyalkylene terephthalate, modified with hydroxy- or carboxy-terminated polystyrene. The blends have good solvent resistance, heat distortion temperature, and gloss. Methods for preparing blends of polyester and polyphenylene ether are also described. They involve modifying the polyester with hydroxy- or carboxy-terminated polystyrene, prior to blending with the polyphenylene ether.
