The invention relates to impact-resistance modified polycarbonate compositions containing A) between 40 and 95 parts by weight of a branched aromatic polycarbonate and/or a branched aromatic polyester carbonate, B) between 1 and 25 parts by weight of a graft polymer containing one or more graft bases (B.2) selected from the silicon rubber (B.2.1) and silicon acrylate rubber (B.2.2) groups, C) between 9 and 18 parts by weight of talcum, D) between 0.4 and 20 parts by weight of a flameproofing agent containing phosphorus, E) between 0.5 and 20 parts by weight of one or more inorganic boron compounds, and F) between 0 and 3 parts by weight of an anti-drip agent. Said compositions meet higher fire-prevention standards. The invention also relates to a method for producing said compositions, to their use in the production of moulded bodies and to thermoformed moulded bodies obtained from said compositions.
L'invention concerne des compositions de polycarbonate à résilience modifiée contenant A) 40 à 95 parts en poids de polycarbonate aromatique ramifié et/ou de polyestercarbonate aromatique ramifié; B) 1 à 25 parts en poids d'un polymérisat greffé contenant une ou plusieurs bases de greffage (B.2) choisies dans le groupe des caoutchoucs de silicone (B.2.1) et des caoutchoucs de siliconacrylate (B.2.2); C) 9 à 18 parts en poids de talc; D) 0,4 à 20 parts en poids d'agent ignifugeant contenant du phosphore; E) 0,5 à 20 parts en poids d'un ou plusieurs composés de bore anorganiques; et F) 0 à 3 parts en poids d'agents anti-gouttes répondant à des exigences augmentées en matière d'ignifugation. L'invention concerne également un procédé de fabrication de ces compositions, leur utilisation dans la fabrication de corps moulés et des corps moulés thermoformés pouvant être obtenus à partir desdites compositions.
