Reactions of PCl/sub 5/ and NH/sub 4/Cl with metal halides yielded compositions composed of a (PNCl/sub 2/)/sub n/ portion linked to the metal halide. Their exact structure was not rigorously established. Most of the compositions are liquids with a wide liquid range and pyrolytic stability at 1100 deg F. Metal halides found to exert this effect are SbCl/sub 5/, SbCl/sub 3/, AlCl/sub 3/, AlBr/sub 3/, BCl/sub 3/, BF/sub 3/, TiCl/sub 4/, and ZnCl/sub 2/. All of the modified products are sensitive to hydrolysis. Two of the AlCl/sub 3/ compositions were successfully distilled. One had a pour point of -55 deg C and a b.p. of 420 deg C/1.1 mm which represents the widest potentially useful liquid range obtained thus far in the project. Viscosity measurements from 0 to 700 deg F indicate the metal halide stabilized phosphonitrilic chloride liquids have satisfactcry temperature-viscosity characteristics. Phenoxy derivatives of cyclic phosphonitrilic chloride trimer, tetramer, oil mixture, and highly polymerized rubber were prepared along with o-biphenylyloxy, mixed phenoxy/o- biphenylyloxy, mixed phenoxy/p-biphenylyloxy, and mixed phenoxy/m-phenoxyphenoxy derivatives of (PNCl/sub 2/)/sub 3/. These compounds, which vary from crystalline solids tc viscous liquids, have good hydrolytic stability, very low vapor pressures, and thermal stability up to about 750 deg F. (auth)
