CATIONIC CONDUCTIVITY IN POLY(OXYETHYLENE OXIDE) NETWORKS

New monomer salts with a perfluorosulfonate group were synthesized. Th ese new salts, bearing one or two double bonds, lead to cross-linked s olvating ionomers. Preliminary ionic conductivities and thermal charac terizations are reported for single-cation conductors polymer electrol ytes. The conductivity values of these single-cation conductors are ma rkedly higher than those reported in the literature; the conductivity loss, with respect to the free-salt complexes, corresponds approximate ly to the expected anionic conductivity. The aim of this communication is twofold: (i) description of the synthesis of new lithium salts, an d (ii) presentation of the results obtained with poly-electrolytes hav ing a grafted anion.
