Abstract

PURPOSE: To prepare a high-polymerization degree phosphazene polymer industrially and advantageously, by heating a phosphazene oligomer in the presence of a Lewis base as a catalyst in a closed system.
CONSTITUTION: (A) A phosphazene oligomer, preferably a mixture of a linear and a cyclic oligomers stabilized with phosphorus pentahalide or a hydrogen halide, comprising 5W95wt% of the linear oligomer, is heated in the presence of (B) a Lewis base, e.g. urea or thiourea, at 150W350°C, preferably 200W300°C, in a closed system to give the title polymer. The amount of (B) is preferably about 0.1W5% based on (A).
