Fundamental Studies and Recent Advances in Anionic Polymerization 5. Assembly and Self-organization of Macromolecules with Hetero-phase Structures Kenji SUGIYAMA Akira HIRAO Polymeric and Organic Materials Department, Graduate School of Science and Engineering, Tokyo Institute of Technology, Meguro-ku, Tokyo, Japan Nippon Gomu Kyokaishi,(2007),80(7),266-272 General Review in Japanese Abstract Morphological studies of well-defined polymers with heterophase structures including AB diblock copolymers, ABC triblock terpolymers, and 3-arm asymmetric ABC star-branched polymers are reviewed. Among them, ABC triblock terpolymers and asymmetric ABC star-branched polymers have been recently synthesized by means of living anionic polymerization. It has been well established as Molau's rule for a long time that the microphase-separated structures observed for AB diblock copolymers are successively changed from spherical, cylindrical, gyroid, to lamellar, depending on the composition f and combination parameter ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() Keywords: Living Anionic Polymerization, AB Block Copolymer, ABA Triblock Copolymer, ABC Triblock Terpolymer, ABC Star-branched Polymer, Microphase Separation, Self-organization, Hetero-phase Structure |
