Copolymers of perfluorotrivinyltriazine compounds and methods for synthesizing the copolymers

Abstract:

Provided herein are copolymers that comprise copolymerized residues of a perfluorotrivinyltriazine monomer of Formula 1. ##STR00001## Preferred R.sub.f groups include, without limitation, --(CF.sub.2).sub.n-- (n=1-6); --(CF.sub.2).sub.m--[OCF(CF.sub.3)CF.sub.2].sub.p-- (m=1-4, p=1-4); and --[(CF(CF.sub.3)--O).sub.x--(CF.sub.2).sub.k]-- (x=1-3, k=1-5). Preferred comonomers for copolymerization with the perfluorotrivinyltriazine monomer (1) include, without limitation, tetrafluoroethylene (TFE); vinylidene fluoride (VF2); hexafluoropropylene (HFP); vinyl fluoride (VF); EVE; PSEPVE; perfluoro-(long chain vinyl ethers); E; P; PFBE; PEVE; EVE-OH; EVE-P; PDD; and the cure-site monomers BTFB, ITFB, 8-CNVE, 8-SAVE, and the like. Also provided are methods of synthesizing the copolymers and articles comprising the copolymers.
