| 1. A polymerization product of a monomeric mixture comprising (a) one or more first monomers of the general formula:
A-L-R1—(X—CF═CF2)n wherein R1 represents one or more inertly substituted groups; X is independently a group which links the inertly substituted groups and
the trifluorovinyl group; L is an optional linking group and is independently a straight or branched C1-C30 alkyl group, a C3-to C30 cycloalkyl group, a C5-C30 aryl group, an ether group, a C1-C20 ester group, an amide group, a siloxanyl, an arylsiloxanyl or a fluorosiloxanyl; A is CO2Z, SO2Z, PO3Z, or OPO3Z wherein Z is hydrogen or an alkali metal and n is an integer of 1 to about 1000; (b) one or more second crosslinking monomers
comprising at least three trifluorovinyl groups and (c) one or more prepolymers comprising one or more trifluorovinyl groups.
