Abstract

The invention relates to thermoplastic molding compounds containing thermoplastic aromatic polycarbonates, thermoplastic copolymers, optionally graft polymers and/or tetrafluoroethylene polymers and/or silicone resins, characterized in that they contain phosphorus compounds corresponding to formula (I) ##STR1## in which R is a --CH.sub.2 --, ##STR2## group and the aromatic radicals may even be alkyl-substituted.
