Abstract

A series of mixed-substituent poly(organophosphazenes) with ethyleneoxy side groups has been synthesized. These polymers possess multiple electron-donor coordination sites that can form complexes with metal salts and generate "solid electrolyte" behavior. The polymers were characterized by 31P, 1H, and 13C NMR spectroscopy, gel permeation chromatography (GPC), differential scanning calorimetry (DSC), and elemental analysis. All the mixed-substituent polymers have low glass transition temperatures, from -70 to -56 °C, as well as at least one melting transition. Several polymer - lithium triflate complexes were examined by impedance analysis. The maximum conductivities for these polymere ranged from 1.6 × 10-6 to 3.9 × 10-5 S cm-1.
