  • Polycarbonate comprising glass fibres
    Patent number: 8916630
    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.
