A new lithium perfluoroakylsulfonate has been synthesized from a commercial perfluorovinylether fitted with a fluorosulfonyl group. By making use of the vinylether group, this species was incorporated into polyurethane networks based either on a poly(ethylene oxide)glycol or on a tri‐arm star‐poly(ethylene oxide)triol. The results, in terms of ionic conductivities, thermal behaviour and different domains of rigidity (solid‐state 1 H NMR), are reported for these single cation conductor polymer electrolytes. When compared to the polymer electrolytes where the same but untethered lithium perfluoroakylsulfonate is dissolved in the same initial networks, a loss of conductivity is observed despite the higher mobility of the ionomers. This loss corresponds to the conductivity attributed to the anionic species. The higher mobility of the ionomeric electrolytes is to be related to the quasi absence of physical crosslinks. © 2000 Society of Chemical Industry
