New salts with monomer functionality and bearing a perfluorosulfonate group have been synthesized. These salts contain one or two carbon double bonds and thus can be incorporated into crosslinked solvating ionomers. Another family possesses epoxy rings and can be copolymerized with ethylene oxide. The results, in terms of ionic conductivities and thermal behavior are reported for these single-cation conductor polymer electrolytes. The conductivity values of these materials are markedly higher than those previously reported for other t(+) = 1 materials. The loss in conductivity, as compared to the untethered salt complexes, corresponds approximately to that attributed to the anionic conductivity. Alkali metals rank in the order sigma(K)- > sigma(Na)- > sigma(Li+).
