    Abstract: A thermoplastic molding composition containing talc is disclosed. The composition wherein talc has a median particle size of less than 1000 nm further contains a polycarbonate and/or polyester-carbonate, and a graft polymer having as graft base a rubber having a glass transition temperature of below about 10° C. is suitable for preparing molded articles having improved mechanical properties, such as weld line strength, elongation at break and toughness at low temperatures.

    Abstract: A mineral-filled, impact-resistant thermoplastic molding composition is disclosed. The composition contains at least one resin selected from the group consisting of polycarbonate and polyester carbonate B) impact resistance modifier, and C) wollastonite having carbon content greater than 0.1% relative to the weight of the wollastonite as determined by elemental analysis. Exhibiting high modulus of elasticity and a good toughness, in particular also at low temperatures, the composition is suitable for car body external applications.

    Abstract: Providing a composition containing aromatic polycarbonate and/or polyester carbonate, graft polymerisate from (meth)acrylonitrile, butadiene, and at least one styrene monomer, obtained in a bulk polymerization process, halogen-free phosphorus compound, fluorinated polyolefin, polymer containing acrylate monomer, and finely divided inorganic materials. A composition containing (parts by weight): (A) aromatic polycarbonate or polyester carbonate or their mixtures (40-95); (B) a graft polymerisate from acrylonitrile and/or methacrylonitrile, butadiene, and at least one styrene monomer, obtained in a bulk polymerization process (5-40); (C) a halogen-free phosphorus compound (0-20); (D) fluorinated polyolefin (0.1); (E) a polymer containing acrylate monomer (0-5); and (F) finely divided inorganic materials of mean particle diameter at maximum 1000 nm, with the proviso that: (i) the polycarbonate or polyester carbonate has a mean number average molecular weight Mw of 25,000 to 35,000; (ii) the graft polymerisate under (B) has a butadiene content of 8-15 wt.% on the graft polymerisate and an acrylonitrile and or methacrylonitrile content of 15-30 wt.% on the sum of the acrylonitrile and/or methacrylonitrile and styrene monomer in the graft polymerisate B and styrene monomer/(meth)acrylonitrile copolymer of weight average molecular weight Mw = 5.104 to 14.104 g/mole. An Independent claim is also included for shaped parts obtained from the composition.
