摘要：
The present invention relates to a process for the preparation of flame-resistant polycarbonate moulding compositions, which is characterized in that, besides the addition of alkali metal salts, there is incorporation of tetrafluoroethylene polymers as an intimate mixture with halogen-free graft polymers, these intimate mixtures being prepared by coagulation of the appropriate emulsion mixtures, and to the polycarbonate moulding compositions obtainable by the process according to the invention.
