Patent number: RE34364Abstract: Aryloxytriazine-capped polyphenylene ethers are prepared by reaction of a polyphenylene ether with an aryloxychlorotriazine such as diphenyl chlorocyanurate. The products undergo reaction with amine-terminated polymers such as polyamides, to form compositions which have excellent properties and which find utility as molding compositions and as compatibilizers for blends of similar polymers.Type: GrantFiled: July 22, 1991Date of Patent: August 31, 1993Assignee: General Electric CompanyInventor: Sterling B.
