ABSTRACT:
A phosphazene composition is prepared by reacting a fully hydrocarboxylated phosphazene with a partially hydrocarboxylated phosphazene under conditions whereby an organic halide is evolved, in which at least one of the fully and partially hydrocarboxylated phosphazenes are prepared by adding an alkali metal hydrocarboxide to a phosphonitrilic halide whereby the final phosphazene composition contains some --P--ONa bonds, as well as --P--O--P--bond configurations. The phosphazene compositions are useful as fire retardants for cellulosics.
