Research progress of synthetizing polydichlorophazene

Polydichlorophazene is a colloidal ivory inorganic polymer with high elastic and an important intermediate that synthetizes polyphosphazene derivatives. By means of substituting the chloridion on polydichlorophazene by nucleophilic group, new functional materials with various different performance are fromed. The paper present research progress of synthetizing polydichlorophazene methods which are consist of two steps: the first step is synthesis of hexachlorocyclotriphosphazene, the second step is synthesis of polydichlorophazene.
