摘要： PROBLEM TO BE SOLVED: To provide an apparatus for continuous polycondensation by which a good-quality polymer can be obtained at good efficiency as a result of the uniform agitation and surface refreshment of the solution to be treated in the body, realized by an impeller having a relatively simple structure, and to provide a method for continuos polycondensation performed therewith 1. SOLUTION: A rotary shaft 2 is provided in the longitudinal direction in the inside of the body 1 of a vertical cylindrical container, and the inside of the body is partitioned with annular members into a plurality of sections, each of which formes a doughnut-like agitation chamber 6. The sides of two adjoining agitation chambers are connected to each other through a connecting pipe 5. Agitating members 7A and 7B for scraping up the liquid in each chamber on the outside wall side and scraping down the liquid on the inside wall side is attached to a rotary axis 2, and a clearance through which volatile matter passes is provided between the inside of the doughnut-like agitation chamber 7 and the rotary shaft 2. Because the liquid can be agitated in the body under the conditions of nearly perfect self-cleaning and is subjected to surface refreshment, a polymer free from deterioration due to excessively long stay and having good quality can be produced at good efficiency.
