Abstract: 1285241 Polymerisation apparatus INVENTA AG FUR FORSCHUNG UND PATENTVERWERTUNG 23 Jan 1970 [24 Jan 1969] 3472/70 Heading B1X [Also in Division C3] Polymerisation reactions, for example polymerisation of caprolactam and the lactam of omega-aminolauric acid and of esters or polyester precondensates are carried out continuously by a method comprising supplying the feed at an elevated temperature which is below polymerisation temperature through pipe 2 to a pipe within an elongated reaction vessel 6 having outlet 5 at one end, the pipe traversing the length of the vessel twice and opening at 4 into the vessel near the end remote from the outlet, the reaction mixture then flowing without disturbance through the vessel to outlet 5. The feed pipe is preferably arranged as shown with a centrally disposed straight limb and a spiral limb. The feed may be preheated in 1 which is temperature regulated by temperature measuring device 11, regulator 10 and steam regulating valve 12. The reactor itself may be jacketed.
