ABSTRACT:
Ionic perfluorovinyl compounds and their uses as components of ionic conductors of the polymer type, of selective membranes or of catalysts. The compounds comprise at least one perfluorovinyl group and at least one group chosen from —O or one of the groups C≡N, —C(C≡N)2, —NSO2R or —C[SO2R]2or a pentacyclic group comprising at least one N, C—C≡N, CR, CCOR or CSO2R group. The compounds and/or their polymers are of use in the preparation of ionically conducting materials, electrolytes and selective membranes.
