New phosphazene-based polymers have been synthesized, which function as single-ion conductors of either sodium or halide ions. As a prelude to the synthesis of these polymers, similar substitution reactions were carried out on hexchlorocyclotriphosphazene and the products were well characterized. The polyelectrolytes were characterized by 1H NMR, 31P NMR, IR, DSC, and ac complex impedance studies. The temperature dependence of the conductivity of these polyelectrolytes follows the VTF equation, indicating that, as with polymer-salt complexes, ion transport is promoted by polymer-segment motion. The ionic conductivity of the polyelectrolytes containing bromide and iodide is 2 orders of magnitude higher than that of the sodium polyelectrolytes at 30-80°C.
