Polycarbonate molding compositions resistant to light aging and exhibiting an improved notched impact strength are disclosed. The compositions which are based on an aromatic polycarbonate, aromatic polyester carbonate or a polyester, contain a redox-catalyzed graft polymer of resin-forming monomers on a rubber, a phosphorus compound and a fluorinated polyolefin.

Polycarbonate molding compounds stable to light ageing

The invention relates to thermoplastic polycarbonate molding compounds containing polycarbonates, copolymers, phosphorus compounds, tetrafluoroethylene polymers and, optionally, graft polymers and also further additives and other thermoplastics and also stabilizers, pigments, flow aids, mold release agents, antistatic agents and/or other flameproffing agents, characterized in that they contain as phosphorus compounds those corresponding to formula (I) ##STR1## and to a process for the production of the polycarbonate molding compounds.

Moulding compositions having flame-resistant properties

The invention relates to a process for the preparation of powder form polymer mixtures consisting of a tetrafluoroethylene polymer and an organic thermoplastic polymer, the tetrafluoroethylene polymer being present in the compositions in a particulate, highly disperse form; the powder form polymer mixtures thereby obtained have special and surprising properties when they are processed in a thermoplastic manner to give plastics articles and when they are added to conventional thermoplastics.
