Flame-retardant impact-modified battery boxes based on polycarbonate i

A composition suitable for use in a battery box comprising

• A) 70.0 to 90.0 parts by weight, relative to the sum of parts by weight of components A+B+C, of linear and/or branched aromatic polycarbonate and/or aromatic polyester carbonate,
• B) 6.0 to 15.0 parts by weight, relative to the sum of parts by weight of components A+B+C, of at least one graft polymer with
• B.1 5 to 40 wt. %, relative in each case to the graft polymer B, of a shell comprising at least one vinyl monomer and
• B.2 95 to 60 wt. %, relative in each case to the graft polymer B, of one or more graft bases consisting of silicone-acrylate composite rubber,
• C) 2.0 to 15.0 parts by weight, relative to the sum of parts by weight of components A+B+C, of one or more phosphorus compounds selected from the groups of monomeric and oligomeric phosphates and phosphonates, phosphonate amines, phosphazenes and phosphinates,
• D) 0 to 3.0 parts by weight, relative to the sum of parts by weight of components A+B+C, of one or more antidripping agents,
• E) 0 to 3.0 parts by weight, relative to the sum of parts by weight of components A+B+C, of thermoplastic vinyl (co)polymer (E.1) and/or polyalkylene terephthalate (E.2), and
• F) 0 to 20.0 parts by weight, relative to the sum of parts by weight of components A+B+C, of one or more further additives,
• wherein the compositions are preferably free from rubber-free polyalkyl(alkyl)acrylate and wherein all stated parts by weight are standardised such that the sum of parts by weight of components A+B+C in the composition is 100.
