    摘要: High molecular weight non cross-linked polyfluoroalkoxyphosphazenes containing some unsaturated groups can be cured (i.e. cross-linked) by contact with a catalyst consisting essentially of platinum, a platinum halide or a haloplatinic acid or their hydrates (e.g. chloroplatinic acid hydrate).

    摘要: Polyetheroxy-substituted polyphosphazenes having reduced mono and polyetheroxy alkanol, alkali metal and halide contaminants that are suitable for use in making solid electrolytes are made by dissolving the impure polyphosphazene in an inert solvent (e.g. tetrahydrofuran) and mixing this solution with a cycloalkane (e.g. cyclohexane) to precipitate the polyetheroxy-substituted polyphosphazene with reduced etheroxy alkanol content. This can be dissolved in water and contacted with an anion exchange material to remove residual halide anions. The purified polyetheroxy-substituted polyphosphazene is then recovered by distilling off the water.
