Patent number: 9068031Abstract: The present invention relates to a reactor (10) and a process for continuous polymerization, where the reactor (10) has an essentially tubular reactor housing (16). The reactor housing (16) has a drive (38) which runs along the geometric central axis (12) in the flow direction (22) and is configured as a central shaft. A rotatably arranged scraper or wiper (36) is provided within the reactor housing (16); the scraper or wiper (36) has at least one scraper or wiper blade (42) to run along an interior side (44) of the reactor housing (16). The rotational movement of the scraper or wiper (36) results in radial mixing of a stream within the reactor housing (16) which dominates gravity effects and, by virtue of shaping of the scrapers or wipers, optionally makes plug flow or a loop flow or backflow within the reactor (10) or else via an additional external pumped circulation system (23) possible.Type: GrantFiled: December 29, 2011Date of Patent: June 30, 2015Assignee: LANXESS INTERNATIONAL SAInventors: Hanns-Ingolf Paul, Rolf Feller, Paul Wagner, John Lovegrove, Joachim Ritter, Ricarda Leiberich, Jörg Kirchhoff, Udo Wiesner
