Abstract: The invention relates to the essentially salt-free coagulation of plastic or rubber dispersions using shearing forces. A device with at least one shearin g element (3) is used to this end. Said device has a stator (7) and a rotor (9 ) which is arranged inside said stator, the surfaces of the stator and the rot or that point towards each other each being flat. Alternatively, at least the rotor has a structure which is configured on its surface and which points in the direction of the stator from said surface. A gap (11) with a predetermin ed gap width is configured between the stator and the rotor. The method is carried out in such a way that the dispersion to be coagulated is guided through the gap (11) between the stator (7) and the rotor (9) and precipitat ed through the rotation of the rotor at a predetermined shear speed and with a predetermined shear deformation.

Abstract: 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.

Abstract: A process for preparation of rubber containing thermoplastic molding compositions in which at least one elastic rubber polymerisate A and at least one thermoplastic polymer B are prepared by polymerization and mixed, with dispersion of polymerisate A, with addition, after polymerization of A, of a pH buffer system after mixing in an aqueous phase, is new. Independent claims are included for: (1) rubber containing thermoplastic molding compositions prepared as above; (2) shaped parts, films, fibers, and foams obtained from the rubber containing thermoplastic molding compositions; and (3) a process for decreasing the mold coating in the production of injection molded parts from the rubber containing thermoplastic molding materials.
