Synthesis and Properties Study of Poly-di(bis-dimethoxy-ethyl) Amine Phosphazene

Poly-di (bis-dimethoxy-ethyl) amine phosphazene was synthesized by nucleophilic substitution reaction with bis (dimethoxy ethyl) amine and conductive polymer materials were manufactured by compositing of the lithium salt and polyphosphazene. The results show that: Td10=503K, the maximum decomposition rate was at 653K. When the mol Li+/ repeat unit was 1.5, the conductivity of polyphosphazene composite conductive material comes up to 4.21×10-8S/cm.
