| Research Abstract |
We have successfully synthesized high-generation dendrimer-like hyper branched mega molecules with well-defined structures by developing a novel iterative methodology based on living anionic polymerization. Furthermore, the synthesis of block polymers consisting of different polymer segments introduced in each generation and the introduction of useful functional groups are also successful, resulting in new precisely designed functional polymers with hyper branched structures. In multiphase block polymers, it is expected to create quite novel nanosupramolecules and assemblies by molecular level phase-separation of each polymer segment, followed by self-organizing and assembling. Some new results have been obtained.
