ABSTRACT:
In a polymerizing apparatus which comprises a polymerization vessel and a circulating line comprising a heat exchanger installed outside said polymerization vessel and a circulating pipeline extending from said polymerization vessel and returning to said polymerization vessel through said heat exchanger, the improvement comprising a strainer installed in the course of said circulating pipeline. Since polymer scale and a polymer in the form of blocks formed in the circulating line can be trapped, the circulating pipeline and tubes of the heat exchanger can be prevented from being blocked up. Further, since they can be prevented from mixing with a reaction mixture in the polymerization vessel, when the obtained polymer is worked into a molded item such as a sheet, fish eyes can be prevented from increasing. Therefore, a polymer can be produced efficiently with high productivity.
