    • 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.
    • 本发明提供具有式A-B的单体,其中A由式I表示:其中B选自-OCF = CF 2和-A; 其中当B为-OCF = CF 2时,B的取向为A的三氟乙烯氧基的间位或对位; 其中,当B为A时,连接A基团的键对于每个A的三氟乙烯基氧基; 并且其中每个Z独立地选自-SO 2 F,-SO 2 Cl,-SO 3 H,-SO 2 -N(M)-SO 2 CF 3和-SO 2 -N(M)-SO 2 R f; 其中M是任何合适的阳离子,Rf是C1至C10碳氟化合物或氟化醚基团。本发明还提供了根据式II的单体:其中X是F,Cl或N(M)SO 2 R f,其中M是任何合适的 阳离子和Rf是C1至C10碳氟化合物或氟化醚基团。
