Abstract: A process is disclosed for continuously preparing polyamides from a mixture of at least one lactam and water, as well as if required other monomer units and/or usual additives and fillers in polyamide-forming conditions. The mixture of initial substances is heated in the liquid phase in a first reaction zone until a conversion rate of at least 70% is reached, then is adiabatically expanded and further polymerised in another reaction zone. In the first reaction zone, 0.5 to 7 % by weight water are added to the mixture, the mixture is heated up to a temperature range from 220 to 310 .degree.C and polymerised until a conversion rate of at least 85 % is reached. In the second reaction zone, after the mixture is expanded, it is further polymerised at temperatures in a range from 215 to 300 .degree.C without further heating.

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.
