Polyphosphazene and molding compound containing the polyphosphazene
12552904 · 2026-02-17 · ·

The invention relates to a polyphosphazene produced by a method comprising the steps a) and b): a) converting an in particular cyclical phosphazene by means of phenol in the presence of a base; b) further converting by means of a special aromatic diphenol in the presence of a base, wherein the molar ratio of phenol used to cyclical phosphazene used is in the range from 3.5:1 to 1:1. The invention also relates to a method for producing the polyphosphazene and to a molding compound containing the polyphosphazene and a thermoplastic polymer.
