Polyphosphazene

Polyphosphazenes are inorganic polymers with a phosphazene repeating unit and general structure (-RR'P=N-). They are generally prepared from the intermediate poly(dichlorophosphazene) and either amines or sodium salts of alcohols. Poly(dichlorophosphazene) is prepared from the ring opening polymerization of hexachlorocyclotriphosphazene.
