Abstract

Flame-retardant thermoplastic molding compositions comprise PA1 A) from 5 to 99% by weight of a thermoplastic polymer, PA1 B) from 0.1 to 50% by weight of a phosphazene of the general formula I EQU (PN.sub.2-x H.sub.1-y).sub.z I PA1 where the numerical values of x, y and z, independently of one another, are as follows: PA2 1>x>0.05 PA2 1>y>0.05 PA2 z>1, and PA1 C) from 0 to 70% by weight of other additives and processing aids, where the total of the percentages by weight of components A) to C) is 100%.
