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.
