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.
本发明提供了具有A—B式的单体,其中A由式I表示:
其中B选自—OCF═CF2和—A;当B为—OCF═CF2时,B的取向为A的三氟乙烯氧基的间位或对位;当B为A时,连接A基团的键对应于每个A的三氟乙烯氧基的对位;每个Z独立选自—SO2F、—SO2Cl、—SO3H、—SO2—N(M)—SO2CF3和—SO2—N(M)—SO2Rf;其中M是任何合适的阳离子,Rf是C1到C10的氟碳或氟化醚基团。
本发明还提供了根据式II的单体:
其中X为F、Cl或N(M)SO2Rf,其中M是任何合适的阳离子,Rf是C1到C10的氟碳或氟化醚基团。
