Abstract

A horizontal solid-bed polymerization reactor which is divided into a plurality of zones, for example a reaction zone, an after-reaction zone, a heating zone and a product discharge zone and possesses inlet and outlet openings for feeding substances into the zones and/or removing substances from the zones, the zones being separated from one another over a part of the reactor cross-section by means of weirs, wherein two drive shafts which are independent of one another and possess mixing elements are introduced into the solid-bed polymerization reactor in the middle.
