Abstract:
1. A flame-retardant, thermoplastic polyamide or polyurethane moulding composition containing A. 1 to 10% by weight of red phosphorus as flame retardant, B. 1 to 15% by weight of a carrier resin for the phosphorus, and C. 0.05 to 8% by weight of an inorganic or organic compound of a di- to tetravalent metal as stabilizer for the phosphorus, wherein the carrier resin B is a low molecular weight polyamide which has a molecular weight of from 500 to 10,000 and a melting point of from 50 to 200 degrees C, and most of whose end groups are blocked.
