Abstract

The present invention relates to a thermoplastic molding composition composed of polycarbonate and inorganic fillers which comprises from 0.01 to 0.5 part by weight of at least one anhydride-modified alpha-olefin terpolymer and which has a high degree of rigidity and nevertheless exhibits good strength, as well as stress-strain characteristics corresponding to those of an unreinforced polycarbonate. Surprisingly, the molding composition additionally exhibits an improvement in flame retardancy. The invention relates in particular to flame-retardant, thermoplastic molding compositions filled with glass fibers, and to the production and use thereof. The property profile is, surprisingly, independent of the degree of interaction of the filler with the polycarbonate matrix.
