Abstract:
An ionically conductive composition comprising a liquid imbibed within an ionomer comprising a backbone and pendant groups, the backbone consisting essentially of methylene and methine units and the pendant groups comprising ionic radicals of the formula--R.sub.f --CF.sub.2 CF.sub.2 --SO.sub.2 --X--(SO.sub.2 R.sub.f).sub.a.sup.- M.sup.+where M.sup.+ is a univalent metal cation; the R.sub.f groups are independently selected from the group consisting of linear or branched perfluoroalkylene radicals, perfluoroalkylene radicals containing O or Cl, and perfluoroaryl radicals; R is hydrocarbyl; a=0-2; and X=O, N or C; said ionic radicals being further limited in that a=0 when X=O, a=when X=N, and a=2 when X=C.
