Title:

MANUFACTURING APPARATUS OF POLYMER, POLYMERIZATION CONTAINER, AND MANUFACTURING METHOD

Document Type and Number:

WIPO Patent Application WO/2010/032302

Kind Code:

A1

Abstract:

A manufacturing apparatus of a polymer including a polymerization container, a bearing part, a protective part, a circulation cooling part, a stock material injection nozzle and a flow path structural means. The protective part forms a first flow path between itself and a side face of a stirring shaft. The circulation cooling means has a circulating inlet nozzle provided on a side face of a protrusion to be opposite to the protective part. The flow path structural part is provided between the bearing part and the protective part to cover the side face of the stirring shaft to fix the bearing part and the protective part. The flow path structural part forms a second flow path between the side face of the stirring shaft and the flow path structural part and a third flow path for coupling the second flow path with the stock material injection nozzle. The first to third flow paths form a continuous flow path, and the uppermost end of the first flow path is opened toward the inside of the protrusion. A gap, the part of the first flow path except the uppermost end, and the second and third flow paths are separated from the inside of the protrusion.
