Abstract

The invention relates to flameproofed, non-dripping polyamide moulding compositions which contain certain amounts of PA0 A) phosphinic acid esters of polyphenols based on phenol-aldehyde/ketone condensates, PA0 B) antidripping agents (such as polyfluoroethylene polymers or aramides) and PA0 C) zinc borate and if appropriate reinforcing agents and other additives for flameproofing and for processing etc.
