Abstract
Polyphenylene ether-polyester copolymers, useful for compatibilizing blends of polyphenylene ethers with polyesters such as poly(alkylene terephthalates), are prepared by heating a polyphenylene ether with a polyester containing olefinic structural units, such as those derived from maleic or fumaric acid.
