Abstract

1,177,978. Polymerizing and extruding polyamides. CESKOSLOVENSKE ZAVODY GUMARENSKE A PLASTIKARSKE OBOROVE REDITELSTVI. 14 Dec., 1967 [27 Dec., 1966], No. 56806/67. Heading B5A. [Also in Division B1] Alkaline catalysed polyamide is both formed and moulded using an apparatus comprising a spiral polymerization reactor 2 connected to a screw extruder 5, the latter having an opening 7 for the evacuation of low molecular weight products, a screw 4 whose thread depth is greatest adjacent opening 7, and a transverse die orifice 8. Spiral reactor 2 may be formed by a coiled tube, or preferably, by grooves in metal sheets. Also, more than one spiral may be used each communicating with screw extruder 5 via an opening 6. A plurality of reactors may be arranged with inlets 1 connected to a common feed and the outlets 3 thereof may be connected to form a common outlet.
