Patent number: 6323279Abstract: A thermoplastic molding composition having little intrinsic color is produced from a graft copolymer and a thermoplastic polymer. The graft copolymer is produced from a soft elastomeric particulate graft base obtained by polymerization of a conjugated diene alone or with a small amount of a monoethylenically unsaturated monomer, upon which is grafted a vinylaromatic monomer and acrylonitrile and optionally another monoethylenically unsaturated monomer. The thermoplastic polymer is a copolymer of a vinylaromatic monomer and acrylonitrile and optionally an additional monoethylenically unsaturated monomer. The thermoplastic molding composition has a low level of intrinsic color coupled with good mechanical properties and can be processed by, for example, extrusion, injection molding, calendaring, blow molding, compression molding, or sintering.Type: GrantFiled: December 30, 1999Date of Patent: November 27, 2001Assignee: BASF AktiengesellschaftInventors: Norbert Güntherberg, Jürgen Koch, Peter Ittemann, Joachim Seibring, Sven Grabowski, Graham Edmund McKee, Norbert Mosbach, Bernhard Czauderna, Norbert Niessner, Hartmut Heinen
