Sulfonated perfluorovinyl functional monomers

Abstract

The present invention provides a monomer having the formula A-B, wherein A is represented by Formula I: wherein B is selected from —OCF═CF2 and —A; wherein, when B is—OCF═CF2, the orientation of B is meta or para to the trifluorovinyloxy group of A; wherein, when B is A, the bond joining the A groups is para to the trifluorovinyloxy group of each A; and wherein each Z is independently selected from —SO2F, —SO2Cl, —SO3H, —SO2—N(M)—SO2CF3, and —SO2—N(M)—SO2Rf; wherein M is any suitable cation and Rf is a C1 to C10 fluorocarbon or fluorinated ether group. The present invention also provides a monomer according to Formula II: wherein X is F, Cl, or N(M)SO2Rf, wherein M is any suitable cation and Rf is a C1 to C10 fluorocarbon or fluorinated ether group.
