    摘要: The present invention relates to flame-resistant moulding compositions of polycarbonates and graft polymers which, in addition to good flow properties, have very good mechanical properties and a particularly good, trouble-free surface. These moulding compositions are suitable in particular for injection moulding uses for mouldings with thin wall thicknesses and high-gloss surfaces. The thermoplastic moulding compositions according to the invention comprise A) 65.0 to 82.0 parts by wt. of at least one aromatic polycarbonate, B) 4.0 to 11.0 parts by wt. of at least one graft polymer, C) 14.0 to 24.0 parts by wt. of at least one phosphorus-containing flameproofing agent, wherein the sum of the parts by weight of components A to C adds up to 100 parts by weight and the total content of the polymer which is formed from the grafting monomers or is added in the free form and is not bonded chemically to the graft base is less than 2.0 wt. %, based on the total moulding composition.
