Abstract

The present invention relates to high-impact, flame-repellant thermoplastic polycarbonate moulding compositions consisting of halogen-free polycarbonates, halogen-free copolymers of styrenes and (meth)acrylonitrile, halogen-free phosphorus compounds of the formula (I) ##STR1## tetrafluoroethylene polymers and small amounts of graft polymers and, if appropriate, effective amounts of stabilizers, pigments, flow control agents, mould release agents and/or antistatics, and a process for their preparation.
