Abstract:
A homo- or copolymeric material comprising the reaction product of one or more compounds of the formulaNâˆ’(SO2XRp)m(SO2Râ€²)o1/nMn+wherein:m is 1 or 2 and m+o is 2; X is independently O or N; p is 1 when X is O, and p is 2 when X is N; R is each independently a monovalent hydrocarbon group; two R groups when taken together form a divalent hydrocarbon group joined to two X atoms, in which the hydrocarbon groups are uninterrupted or interrupted by a heteroatom; or two R groups when taken together may form a three- to six-membered ring with a nitrogen atom, which ring may be further interrupted by a heteroatom; Râ€² is each independently a hydrocarbon group or a straight or branched acyclic fluoroalkyl group having from 1 to 12 carbon atoms, a cyclic fluoroalkyl group having from 3 to 12 carbon atoms, or a fluorocycloalkyl-fluoroalkyl group where the fluoroalkyl group has from 1 to 4 carbon atoms, in which the fluoroalkyl and fluorocycloalkyl groups are uninterrupted or interrupted by a heteroatom; or an R group and an Râ€² group when taken together may form a ring, which ring may be further interrupted by a heteroatom; wherein R or Râ€² contain a polymerizable group; and Mn+ is a cation having a valence of n.
