Abstract: A process is claimed for the prodn. of impact-modified thermoplastics (I) by (a) mechanical dehydration of a moist elastomer component (A) contg. up to 60 wt% residual water and (b) mixing the dried elastomer obtd. (A') with a thermoplastic polymer (B) in a screw machine. The process is carried out in a twin screw extruder with synchronous double-threaded screws and with the following sequence in the direction of feed: (1) a metering section for introducing component (A) into the extruder via a metering device, (2) squeezing section(s) for removing the water, with accumulator element(s) and associated water outlet(s), (3) section(s) fitted with a feeder screw or with mixing, kneading and/or other plasticising elements, (4) section(s) in which polymer (B) is added as a melt, (5) section(s) fitted with mixing, kneading and/or other plasticising elements, (6) degassing section(s) with gas outlets, in which residual water is removed as vapour, and (7) a discharge zone. The water emerging from the outlets in section (2) is partly or completely in the liq. phase, and the extruder is operated at a screw speed of 50-600 r.p.m., with a mean shear rate of 20-240 s . Also claimed are impact-modified thermoplastic moulding materials (I) obtd. by this process.
