Copolymer-containing compositions are prepared by the reaction of an epoxytriazine-capped polyphenylene ether with another polymer containing amine end groups, especially a polyamide, under intimate blending conditions. The compositions have excellent properties and find utility as molding compositions and as compatibilizers for blends of similar polymers. Suitable epoxytriazine-capped polyphenylene ethers may be prepared by reaction of a polyphenylene ether with an epoxychlorotriazine such as diglycidyl chlorocyanurate, n-butyl glycidyl chlorocyanurate or mesityl glycidyl chlorocyanurate.
