    Abstract: The invention relates to a mixing device comprising at least one screw injection moulding machine (S1) and a screw injection moulding machine (S2). (S1) is provided with heating devices at least in the plasticising and homogenising section, and the outlet pertaining to (S2) is connected to the screw cylinder of (S1) in the plasticising or homogenising section pertaining to (S1). It is essential that (S1) and (S2) are connected by means of a connecting device provided with a cooling device which acts up to the inner wall of the screw cylinder of (S1). The invention also relates to methods for producing thermoplastically processable moulding materials, especially additive batches, consisting of at least one thermoplastic component (K1) and at least one component (K2). The melting or decomposition temperature (TS ) of (K2) is at least ca. 50 DEG C lower than the temperature (TW ) which limits the lower end of the thermoforming range of (K1), (K2) only largely being melted after coming into contact with (K1).

    Abstract: Prepn. of deep draw-modified thermoplastics (T) by mechanical dewatering of a wet elastomer component (A) contg. up to 50 wt.% residual water and mixing dewatered (A) with a thermoplastic polymer (B) in a screw - by adding (A) to a twin-screw extruder with 3-way rotating screws. This extruder contains the following sections (in the direction of flow): (1) feed for adding (A) to the extruder; (2) at least one crusher for dewatering (A) that contains one or more barriers each with an opening through which at least some of the water passes as a liq.; (3) at least one section to which molten (B) is added; (4) one or more sections with mixing, kneading and/or plasticising devices; (5) at least one degassing section with one or more gas outlets through which water is removed as steam; and (6) an exit zone.

    Abstract: A process is claimed for the prodn. of impact-modified thermoplastics (I) by mixing a moist elastomer component (A) contg. up to 60 wt% residual water with a thermoplastic polymer (B) and other polymers (C) and additives (D) in a screw machine, with mechanical dehydration of component (A). The process is carried out in a synchronous twin screw extruder with the following sequence of sections in the direction of feed: (1) metering section(s) for introducing component (A) into the extruder by means of a metering device, (2) squeezing section(s) for removing the water, with accumulator element(s) and associated water outlet(s), (3) section(s) in which polymer (B) is added as a melt, (4) section(s) fitted with mixing, kneading and/or other plasticising elements, (5) 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; components (C) and/or (D) are added in one or more of the above sections, either together or separately and together with or apart from (A) and/or (B). Also claimed are impact-modified thermoplastic moulding materials (I) obtd. by this process.

    Abstract: The prepn. of deep draw-modified thermoplastics (T) is by mechanical dewatering of a wet elastomer component (A) contg. up to 50 wt.% residual water and mixing dewatered (A) with a thermoplastic polymer (B) in a screw - by adding (A) to a twin-screw extruder with rotating screws.
