Abstract
A graft copolymer having a side chain graft-polymerized by atom transfer living radical polymerization (ATRP) on a main chain polymerized by organotellurium-mediated living radical polymerization (TERP), wherein the molecular weight distribution is such that Mw/Mn is 1.5 or less. The graft copolymer is also such that a main chain moiety mainly consisting of the main chain and a side chain moiety mainly consisting of the side chain have microphase-separated structures. The graft copolymer has a narrow molecular weight distribution and forms microphase-separated structures through self organization of hydrophobic and hydrophilic moieties.
