GRAFT COPOLYMER AND PROCESS FOR PRODUCING THE SAME

摘要

A graft copolymer comprising a main chain polymerized by the use of organotellurium-mediated living radical polymerization process (TERP process) and, bonded thereto, a side chain graft polymerized by the use of atom transfer radical polymerization process (ATRP process), which graft copolymer has a molecular weight distribution of = 1.5 Mw/Mn and has a micro-phase separation structure of main chain parts consisting mainly of main chains and side chain parts consisting mainly of side chains. The graft copolymer has a narrow molecular weight distribution and forms a micro-phase separation structure through self organizing of hydrophobic parts and hydrophilic parts.
