ABSTRACT:
Alkylated phosphazene oligomers of the general formula (NP(X.sub.2)).sub.n PRH, wherein X represents chlorine or bromine, R represents a linear or branched alkyl, and n represents an integer from 2 to 8, are prepared by reacting, in a nonoxidizing atmosphere, a perhalopolyphosphazene, a Grignard reagent, and a cuprous complex in solution, followed by the addition of a secondary or tertiary alcohol. Polymers useful as high-temperature elastomers, are prepared from the halo-substituted oligomers by heating them at a temperature from about 200.degree. C. to about 300.degree. C., followed by a reaction with an amine, metal alkoxide, or a metal aryloxide at a temperature from 20.degree. to 200.degree. C.
