Patent ID: 7220790

Claim:
A thermoplastic molding composition comprising A) 50 to 80 parts by weight of at least one member having weight average molecular weight of 25,000 to 35,000 g/mol, selected from the group consisting of aromatic polycarbonate and polyestercarbonate, B) 7 to 30 parts by weight of ABS graft polymer produced by the mass polymerization process from at least one of acrylonitrile and methacrylonitrile, further butadiene and at least one styrene monomer, said graft polymer (i) having a butadiene content of 11 to 14 % in relation to the weight of the graft polymer, and (ii) having a (meth)acrylonitrile content of 15 to 30 % in relation to the total weight of the (meth)acrylonitrile and styrene monomer in said graft polymer, and (iii) containing styrene monomer-(meth)acrylontrile copolymer having a weight average molecular weight of 5·10 4 to 14·10 4 g/mol. C) 2 to 18 parts by weight of a halogen-free phosphorus compound, D) 0 to 1 parts by weight fluorinated polyolefin, E) 0 to 5 parts by weight of a polymer containing acrylate monomer and F) 0 to 3 parts by weight of an inorganic material in particulate form with an average maximum particle diameter of no more than 1000 nm, said parts by weight totaling 100.
