The present invention provides a monomer having the formula A-B, wherein A is represented by Formula I:
1
wherein B is selected from —OCF=CF
2
and —A; wherein, when B is—OCF=CF
2
, 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 —SO
2
F, —SO
2
Cl, —SO
3
H, —SO
2
—N(M)—SO
2
CF
3
, and —SO
2
—N(M)—SO
2
Rf; wherein M is any suitable cation and Rf is a Cl to CIO fluorocarbon or fluorinated ether group.
The present invention also provides a monomer according to Formula II:
2
wherein X is F, Cl, or N(M)SO
2
Rf, wherein M is any suitable cation and R
f
is a C1 to C10 fluorocarbon or fluorinated ether group.
本发明提供了一种具有A-B式的单体,其中A由式I表示:1,其中B选自—OCF=CF2和—A;其中,当B为—OCF=CF2时,B的取向为与A的三氟乙烯氧基相对的间位或对位;当B为A时,连接A基团的键为与每个A的三氟乙烯氧基对位;且其中每个Z独立地选自—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Cl到CIO的氟碳化合物或氟化醚基团。本发明还提供了一种根据式II的单体:2,其中X为F、Cl或N(M)SO2Rf,其中M是任何合适的阳离子,Rf为C1到C10的氟碳化合物或氟化醚基团。
