ABSTRACT:
A 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.
