Abstract
An A-B-A type of block copolymer consisting of polymer block A of (meth)acrylate and polymer block B of olefin, having a Mw/Mn of 1.0 to 2.5, is disclosed. This block copolymer can be produced by polymerizing an olefin using a particular rare earth compound as an initiator, and then polymerizing the formed polymer with a (meth)acrylate.
