Abstract

Novel polyelectrolytes were synthesized by quaternization of the backbone of poly(alkoxy- and aryloxyphosphazenes) with strong alkylation reagents. As models for the synthesis of these polymers, similar quaternization reactions were also carried out on small-molecule alkoxy and aryloxy cyclotriphosphazenes. The quaternized small molecules and high polymers were characterized by ¹H NMR, ³¹P NMR, DSC, TGA, and AC impedance studies. The quaternized poly(alkoxyphosphazenes) showed ionic conductivities of 2.58 × 10 ^-4 S•cm ^-1 at 25 °C and 2.09 × 10 ^-3 S•cm ^-1 at 80 °C, which are among the highest values for known solvent-free ionically conducting polymers.
