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

Battery box comprising a composition comprising

• A) 70.0 to 90.0 parts by weight, relative to the sum of parts by weight of components A+B+C, of at least one 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 95 parts by weight of a mixture of
• B.1.1) 50 to 95 parts by weight of styrene, α-methylstyrene, methyl ring-substituted styrene, C1-C8 alkyl methacrylate, C1-C8 alkyl acrylate, and/or a mixture thereof, and
• B.1.2) 5 to 50 parts by weight of acrylonitrile, methacrylonitrile, C1-C8 alkyl methacrylates, in particular methyl methacrylate, C1-C8 alkyl acrylate, maleic anhydride, C1-C4 alkyl or phenyl N-substituted maleinimides and/or a mixtures thereof, on
• B.2) 5 to 95 parts by weight of a rubber-containing graft base based on butadiene or acrylate,
• 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 group consisting 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 optionally 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.
