    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. Also claimed are deep draw-modified moulding materials prepd. by this process.
