Abstract

The present invention relates to flame-retarding, thermoplastic polycarbonate moulding materials of high impact strength consisting of halogen-containing polycarbonates, copolymers formed from styrenes and (meth)acrylonitrile, phosphorus compounds of the formula (I) ##STR1## tetrafluoroethylene polymers and small amounts of graft polymers and, if appropriate, effective amounts of stabilizers, pigments, lubricants, mould release agents and/or antistatic agents, and to a process for the preparation thereof.
