Abstract
Functionalized polyphenylene ethers are prepared by reacting a polyphenylene ether with a polymerizable olefinic compound containing a phosphorus or silicon atom or an epoxy or lactam group, preferably in the presence of a free radical initiator. They may be used in the preparation of compatible polyphenylene ether blends with such polymers as polyesters and polyamides.
