Star-block copolymer (core : polystyrene (PSt), shell : polyethylene glycol (PEG)) was synthesized by a Williamson ether reaction of polyethylene glycol monomethylether (PEG-OH) with the star shaped PSt end-functionalized with tosylate groups that was prepared by a living anionic polymerization and quantitative functionalization reactions. These star polymers containing PEG segment showed a potential ionic conductivity depending on their star-branching structures without any crystallization behavior of PEG segments. In addition, rather high Li ion transport number (φ = 0.241) was observed for starPEG-b-PSt while liner PEG usually showed a low value (φ = 0.1).
