Abstract

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.
