摘要： A process is disclosed for producing thermoplastics modified to be impact-resistant or polymer blends containing such modified thermoplastics. The thermoplastics or polymer blends contain: (A) 5 to 95 wt % of at least one water-wet elastomer component A which contains up to 60 wt % residual water; (B) 5 to 95 wt % of at least one thermoplastic polymer B; (C) 0 to 95 wt % of at least another polymer C; and (D) 0 to 70 wt % additives D. The elastomer component A is mixed with the thermoplastic polymer B, if available with the other polymer C and if available with the additives D in a screw-machine while mechanically dewatering the elastomer component A. The process is characterised in that components A, B, C and D are supplied to an extruder with at least two screws that rotate in the same or opposite directions and have a diameter Dscrew. Seen in the feeding direction (downstream), the extruder substantially consists of at least one dosing section in which the elastomer component A is supplied to the extruder by a dosing device; at least one squeezing section for dewatering the elastomer component A having at least one pressure element and at least a corresponding dewatering opening located upstream of the (first) pressure element at a distance therefrom equal to at least one screw diameter Dscrew; at least one feeding section in which the thermoplastic polymer B is fed into the extruder as a molten mass; at least one plasticising section fitted with mixing and/or kneading elements; at least one degassing section with at least one degassing hole in which the residual water is removed as steam; and an extraction zone. The water expelled through the dewatering openings is partially or totally present in the liquid phase, and components C and/or are supplied together or separately, either together with components A and/or B or separately from A and B in one or more of the above-mentioned extruder sections.
