Abstract

The invention relates to flameproofed non-drip polyamide molding compounds which contain certain quantities of PA0 a) phosphinic acid esters of polyphenols still containing free phenolic OH groups, PA0 b) zinc borate and/or zinc oxide, PA0 c) thermoplastics having a predominantly aromatic main chain, optionally PA0 d) antidripping agents (for example polyfluoroethylene polymers) and, optionally, reinforcing materials and/or mineral fillers and other additives for processing, stabilization, etc.
