Abstract : A series of fully substituted poly(phosphazenes) with alkoxy sidechains, and/or dialkoxy crosslinks were synthesized and investigated as electrolyte host materials. All of the polymers readily formed complexes with LISO3CF3, LIDO3C4F9 and Li2(SO3)2C2F2. The polymer with seven ether oxygens in its sidechain gives the highest conducting polymer salt complex at 30C. The crosslinked polymers were found to be totally amorphous with comparable conductivity and increased resistance to flow at elevated temperatures.
