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.
