Abstract
Substituted alkoxy- or alkylthiochlorotriazines wherein the substituents on the alkoxy groups are chlorine, bromine or dialkylphosphato are useful as capping agents for polyphenylene ethers. The capped polyphenylene ethers form copolymers with other polymers containing nucleophilic groups, including polyesters, polyamides and functionalized olefin polymers. Such copolymers serve as compatibilizers in the formation of blends having high impact strength.
