Abstract

Flameproofed thermoplastic molding compositions contain PA0 (A) 10-99% by weight of a thermoplastic polyamide or polyester or polyphenylene ether or a mixture thereof, PA0 (B) 1-50% by weight of red phosphorus having a particle size of up to 2 mm which contains, per 100 parts by weight, from 0.05 to 5 parts by weight of a polyurethane or polyester-polyurethane as phlegmatizer, PA0 (C) 0-60% by weight of a fibrous or particulate filler or a mixture thereof and PA0 (D) 0-20% by weight of an elastomeric polymer.
