ABSTRACT:
High molecular weight phosphonitrillic chloride polymers that are soluble in benzene, toluene and tetrahydrofuran, tetrameric phosphonitrilic chloride, or mixtures thereof at elevated temperatures in the presence of a catalytic amount of an aprotic Lewis acid halogen acceptor. For example, soluble high molecular weight phosphonitrillic chloride can be made by heating the aforementioned trimer at 220.degree.-270.degree. C. in the presence of 5-1000 ppm of AlCl.sub.3.
