Abstract: Akind of reactive inorganic polymer-poly(dichloro)phosphazene was prepared by ring-opening polymerization at a high temperature.Then a new conductive polyphosphazene containing pyrrole groups was synthesized by nucleophilic reaction between the inorganic polymer and sodium salts of N-hydroxyethylpyrrole.The chemical structure and properties of the polymers were characterized by 1H, 31PNMR, FTIR, DSC, TGA and GPC.The experimental results indicate that the molecular weights of pyrrole-containing soluble polymer are Mn=4.1×105, Mw=9.2×105( Mw/ Mn=2.24) and the Tg is 237 K.Ahigh qulity film was obtained from the soluble polymer through spin-coating method.Using FeCl3as oxidiant, the polymer film underwent crosslinking reaction to form conjugated polypyrrole.After the oxidation reaction, the color of polymer film turned into light black from almost transparent and the conductivity was determined to be 1.7×10-5S/cm, it is 1×105times greater than that of the original film.The crosslinked polymer shows a high thermal stability.

Key words: Polyphosphazene, Ring-opening polymerization, N-Hydroxyethylpyrrole, Oxidation crosslinking
