Abstract

The present invention relates to flame-retarding moulding compositions which are based on thermoplastic polycarbonates, copolymers of styrenes and maleic anhydride, phosphorus compounds of the formula (I) ##STR1## tetrafluoroethylene polymers, small amounts of graft polymers and optionally halogen compounds and which in addition can contain stabilizers, pigments, flow agents, release agents and/or antistatics, and to a process for their preparation.
