Abstract:
1. A polymerization processor comprising: a reactor comprising two or more reaction tanks connected in series, the reaction tank in the final stage having an agitator placed with its rotation axis substantially vertical to the ground, the agitator comprising a double-shaft mixer having a plurality of agitation blades in which agitating blades of each rotation shaft are placed in staggered form, a supply port provided at an upper part of the reaction tank in the final stage, a discharge port provided in a lower part of the reaction tank in the final stage, and a heating jacket including a heat medium configured so that a temperature of the heat medium is at a high level in an area near the discharge port of the reaction tank in the final stage and the temperature of the heat medium is at a low level in an area near the supply port of the reaction tank in the final stage, wherein the reaction tank in the final stage is configured to control efficient removal of heat in selected areas by at least one of (a) being segmented into a plurality of areas so that the temperature of the heat medium can be at a high level in an area near the discharge port of the reaction tank in the final stage and at a low level in an area near the supply port of the reaction tank in the final stage and (b) provided with irregularities on its side face; and an apparatus, connected to the discharge port of the reaction tank in the final stage, for removing remaining raw material from reaction solution discharged from the reaction tank in the final stage.
