Described is a process for the preparation of an acrylic acid ester polymer, which comprises carrying out polymerization of an acrylic acid ester or block copolymerization of an acrylic acid ester and another (meth)acrylic monomer in the presence of an organolithium compound and an organoaluminum compound represented by the following formula:
AlR1R2R3
wherein R1 represents an alkyl group having at least 3 carbon atoms, an alkoxy group having at least 3 carbon atoms or an aryloxy group, R2 and R3 each independently represents an aryloxy group or may be coupled together to form an arylenedioxy group, which process makes it possible to heighten the reaction rate and living properties upon polymerization and heighten the block formation efficiency upon block copolymerization.
