POLYMERIZATION AND RING EQUILIBRATION TRIFLUOROETHOXY-CHLORO-CYCLOTRIPHOSPHAZENES

摘要

The synthesis of phosphazene polymers and copolymers by a procedure in which up to three chlorine atoms in hexachlorocyclotriphosphazene are replaced with alkoxy or aryloxy groups and the resulting compounds are thermally polymerized to yield polymers with a desired distribution of substituents. These may be further modified by replacement of the remaining chlorine atoms with other substituents. Further the polymerization of mixtures containing polychlorocyclotriphosphazenes and various amounts of the cyclotriphosphazenes in which some of the chlorine atoms have been replaced, is also described. The products of said reaction are useful in the production of flame resistant foams, and are resistant to oil and other fluids.
