NOVELTY - Battery housing comprises composition comprising (a) aromatic polycarbonate and/or -polyester carbonate, (b) at least one graft polymer with (bi) mixture of (bi.i) styrene, alpha -methyl styrene, methyl center substituted styrene, 1-8C alkyl methacrylate and/or 1-8C alkyl acrylate and (bi.ii) acrylonitrile, methacrylonitrile 1-8C alkyl methacrylate, 1-8C alkyl acrylate, 1-4C-alkyl and/or -phenyl-N-substituted maleimides, and (bii) rubber-containing graft base, (c) phosphorus compound, (d) anti-dripping agent, (e) thermoplastic vinyl (co)polymer and/or polyalkylene terephthalate, and (f) additives.    USE - The battery housing is useful for automotive batteries and accumulators, motor vehicle, buses, trucks, motor homes, trains, aircraft, water vehicles or other vehicles, stationary batteries, e.g. in buildings for emergency power supply.    ADVANTAGE - The battery housing comprises the composition exhibiting good impact strength at low temperature, high joint line strength, good flame retardancy and good chemical resistance.    DETAILED DESCRIPTION - Battery housing comprises composition comprising (a) 70-90 parts by weight of optionally branched aromatic polycarbonate and/or aromatic polyester carbonate (based on the sum of the parts by weight of components (a)-(c)), (b) 6-15 parts by weight of at least one graft polymer (based on the sum of the parts by weight of components (a)-(c)) with (bi) 5-95, preferably 30-80 parts by weight of a mixture of (bi.i) 50-95 parts by weight of styrene, alpha -methyl styrene, methyl center substituted styrene, 1-8C alkyl methacrylate, preferably methyl methacrylate and/or 1-8C alkyl acrylate, preferably methyl acrylate and (bi.ii) 5-50 parts by weight of acrylonitrile, methyl acrylonitrile 1-8C alkyl methacrylate, preferably methyl methacrylate, 1-8C alkyl acrylate, preferably methyl acrylate, maleic acid anhydride, 1-4C-alkyl and/or -phenyl-N-substituted maleimides, and (bii) 5-95, preferably 20-70 parts by weight of a rubber-containing graft base based on butadiene or acrylate, (c) 2-15 parts by weight of phosphorus compound comprising mono- and oligomeric phosphoric and phosphonic acid ester, phosphonate amine, phosphazene and/or phosphinate (based on the sum of the parts by weight of components (a)-(c)), (d) 0-3 parts by weight of anti-dripping agent (based on the sum of the parts by weight of components (a)-(c)), (e) 0-3 parts by weight of thermoplastic vinyl (co)polymer (ei) and/or polyalkylene terephthalate (eii) (based on the sum of the parts by weight of components (a)-(c)), and (f) 0-20 parts by weight of additional additives (based on the sum of the parts by weight of components (a)-(c)). An INDEPENDENT CLAIM is also included for producing the battery housing comprising injection molding or thermally molding the composition.
