    摘要： In anionic polymerization using an anionic polymerization initiator, a tertiary organoaluminum compound (A) having in the molecule thereof a chemical structure represented by a general formula: Al—O—Ar wherein Ar represents an aromatic ring, and at least one Lewis base (B) selected from the group consisting of a tertiary polyamine compound, are caused to be present in the polymerization system. In this way, the polar monomer can be polymerized with a high polymerization initiation efficiency and a high living polymerization property and at a high polymerization rate even if the used polymerization initiator is suitable for industrial use, and a relatively mild cooling condition or a temperature condition near room temperature is adopted as a polymerization temperature condition.

    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.
