Abstract

The subject of the invention is flameproofed, non-dripping polyamide moulding compounds which contain specific amounts of the following: PA0 A) Phosphinic acid esters of polyphenols based on phenolaldehyde/ketone condensates, PA0 B) Anti-dripping agents (such as polyfluoroethylene polymers or aramides), PA0 C) Zinc borate, PA0 D) Thermoplastics with a predominantly aromatic main chain and a high thermal deflection temperature (Vicat B.gtoreq.180.degree. C.), and, if applicable, reinforcing agents and other additives for flameproofing and processing.
