Abstract
Epoxide-functionalized polyphenylene ethers, which may be prepared by the reaction of various acid-functionalized polyphenylene ethers with functionalized epoxides, 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.
Claims7
A resinous composition comprising at least one polyphenylene ether and at least one polyamide, at least a portion of said polyphenylene ether being an epoxidefunctionalized polyphenylene ether having the formula ##STR11## wherein A is a polyphenylene ether moiety, R.sup.2 is a C.sub.(1-4) alkylene radical, R.sup.5 is an aromatic hydrocarbon radical, and p is 1 or 2.
