Polyphosphazene and moulding compound comprising the polyphosphazene

Abstract

Provided is a polyphosphazene produced by a cyclic phosphazene of formula (1) wherein k is a natural number between 1 and 10, with a bis-hydroxy-terminated phosphonate of formula (2) HO—R2—[O—P(O)(R1)—O—R2]a—OH (2), wherein R1 represents C1- to C20-alkyl, C2-C20 alkylene, C5-C20 cycloalkyl or C6-C20 aryl, R2 represents C1- to C20-alkyl, phenyl or a bisphenyl, and n represents 1-10, in the presence of a base. Also provided is a process for producing the polyphosphazene, a moulding compound comprising the polyphosphazene and a thermoplastic polymer.
