Process for preparing polymers of vinyl monomers with narrow molecular

Polymer compositions for graft copolymer as well as mixtures thereof and

Functionalized copolymers, process for their production, moulding

Thermoplastic molding materials contain A) from 50 to 99% by weight, based on the total weight of the molding material, of a toughened polymer, B) from 1 to 20% by weight, based on the total weight of the molding material, of a blend of

Dulled thermoplastic molding material

Dulled thermoplastic molding materials

Essentially dry materials are obtained by mechanically dewatering water-moist rubber, prepared by emulsion polymerization and precipitation, to give a compact material having a rubber content of at least 50%, by a process in which the previously dewatered rubber is fed to the feed section of a twin-screw extruder which has screws rotating in the same direction and possesses, in succession in the conveying direction, at least two back-up zones and two associated dewatering orifices, each of which may be provided with a retaining screw, and at least one kneading zone, one devolatilization zone and finally one discharge zone, which may be closed by a die lip, and the water separated off is discharged at the dewatering orifices in liquid form.
