Abstract: The invention relates to an extrusion device, particularly an extrusion device for thermoplastic or dough-like masses or highly tenacious melts, and to the use of said device. The extrusion device has a housing (11), at least one conveyor worm (12) arranged in a housing and an outlet (20) disposed on the front face of the housing (11) close to the end of each conveyor screw which is furthest away from the drive end. At least one stripping member (21) is arranged in between the end (14) of each conveyor screw (12) furthest away from the drive end and the outlet (20). The device is particularly suitable for producing granulates, preferably those containing active substances.

Abstract: Thermomechanical degradation of polyolefin(s) is carried out in a twin-screw extruder without the use of any additional degradation appts., at 300-500 degrees C and 1-100 bar over a mean dwell time of 0.5-10 min., during which the pressure is (a)periodically altered by 0.5-30 bar. Low molecular wt. polyolefin waxes prepd. by this method are also claimed.

Abstract: Extrudable pharmaceutical mixtures are tableted by a continuous method in which the mixture is extruded and the still deformable extrudate is pressed between two rollers which are driven in opposite directions and possess depressions opposite one another in the roller shell, the form of these depressions determining the tablet shape.
