Abstract
Carbodiimide-functionalized polyphenylene ethers, which may be prepared by the reaction of various acid-functionalized polyphenylene ethers with polycarbodiimides, are useful in the preparation of polyphenylene ether copolymers. These copolymers are, in turn, useful for the compatibilization of blends of polyphenylene ethers with such other polymers as polyesters and polyamides.
