PROCESS FOR CONTINUOUSLY PRODUCING (METH)ACRYLIC ESTER POLYMER OR COPOLYMER

摘要

A continuous production process, which can allow polymerization to proceed at a milder polymerization temperature and a higher polymerization speed as compared with the conventional method while maintaining a high level of living properties and can produce an (meth)acrylic ester (co)polymer having a narrow molecular weight distribution in a high yield with good productivity. The continuous production process for producing an (meth)acrylic ester (co)polymer comprises the step of continuously feeding an organoaluminum compound-containing polymerization Initiator solution and an (meth)acrylic ester into a reactor to continuously obtain a living polymer- containing polymer reaction liquid. The {[molar quantity of methacrylic ester or acrylic ester]/([molar quantity of organoaluminum compound] - [molar quantity of polymerization Initiator])} fed into the reactor is regulated to be 15 to 80, and the content of the (meth)acrylic ester in the total feed amount of a polymerization Initiator solution and an (meth)acrylic ester fed into the reactor is regulated to not more than 5% by mass.
