ABSTRACT:
Hydroxyalkyl- and aminoalkyl-functionalized polyphenylene ethers are prepared by the reaction of polyphenylene ethers with bis-hydroxyalkyl maleates or fumarates, or with the corresponding acids or anhydrides, terephthaloyl chloride or the like followed by esterification or imidization with diols, diamines or amino alcohols. They are useful in the preparation of polyphenylene ether copolymers, which in turn are useful for the compatibilization of blends of polyphenylene ethers with linear polyesters.
