The polymerization of hexachlorocyclotriphosphazene (I) (also known as phosphonitrilic chloride trimer) to high molecular weight poly(dichlorophosphazene) (II) has been studied in the presence of phosphorus pentachloride, water, and hydrogen chloride. Phosphorus pentachloride is a powerful polymerization inhibitor, water is a polymerization catalyst or cocatalyst, and hydrogen chloride is a mild inhibitor. The results are discussed in terms of possible reaction mechanisms.
