Abstract: The invention is directed to a process for producing a ABS composition comprising 30-80 wt.-% of copolymer A, 19.99-60 wt.-% of ABS-copolymer B, 0-40 wt.-% of polymer C and 0.01-20 wt.-% of additives D, having the steps: a) mixing the components A, B and D and optionally C, by using an extruder comprising: a first feeding zone FZ1, a preheating zone PZ, a mechanical dewatering zone DZ, in which component B is mechanically dewatered, and wherein: the mechanical dewatering zone DZ comprises at least one dewatering aperture, in particular for liquid water; in a second feeding zone FZ2, at least part of component A and optionally part of component D are fed, preferably in melt and/or solid form, to the ex-truder, in a degassing zone DG component A and/or component B are degassed, and b) removing the ABS molding composition from a discharge zone CZ of the extruder.

Abstract: The invention is directed to a process for producing a ABS composition comprising 30-80 wt.-% of copolymer matrix A, 19.99-60 wt.-% of ABS-copolymer B, 0-40 wt.-% of polymer C and 0.01-20 wt.-% of additives D, having the steps: a) mixing the components A, B and D and optionally C, by using an extruder comprising: a first feeding zone FZ1, a mechanical dewatering zone DZ, in which component B is mechanically dewatered, and wherein: the mechanical dewatering zone DZ comprises at least one dewatering aperture, in particular for liquid water, wherein the mechanical dewatering DZ zone comprises one or more elements made of a stainless steel material; in a second feeding zone FZ2, at least part of component A and optionally part of component D are fed, preferably in melt and/or solid form, to the extruder, in a degassing zone DG component A and/or component B are degassed, and b) removing the ABS molding composition from a discharge zone CZ of the extruder.
