Abstract

We report the synthesis and characterization of new linear and crosslinked phosphazene polymers which are suitable solid electrolyte host materials. The effect on the physical properties of variations of the side chain length in a series of poly(alkoxy)phosphazene, left brace NP left bracket O)C//2H//4O) xCH//3 right bracket //2 right brace //n (x equals 1,2,7,12 and 17), salt complexes was investigated. A polymer salt complex with a conductivity of 5. 3 multiplied by 10** minus **5 Scm** minus **1 was obtained at 30 degree C when x equals 7 with LiSO//3CF//3. For x equals 2 crosslinks were introduced by glycol bridges. Polymer-salt complexes of the crosslinked material have vastly improved dimensional stability and conductivities comparable to their linear analogs.
