METHOD OF CONTINUOUS POLYMERIZATION OF POLYMER AND POLYMERIZATION EQUIPMENT THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a method of continuous polymerization of a polymer, by which the accurate component concentration of each monomer component including a monomer component of nonpolymerization reaction recovered by a monomer recovery process in a monomer adjusting part is automatically and continuously controlled and a polymerization equipment therefor. SOLUTION: Unreacted monomer components of polymerization occurring in the polymerization of two or more component-based monomers are recovered by a monomer adjusting tank (3) and the recovered monomer components are continuously returned to the monomer adjusting tank (3). The flow rate and the component concentration of the recovered monomer component returned to the monomer adjusting tank (3) are measured. The feed flow rate of each component monomer fed to the monomer adjusting tank (3) is automatically controlled based on the measured results and the composition concentration of a polymer formed in a polymerization reactor (4) is made constant.
