| Outline of Final Research Achievements |
We demonstrated a precise synthesis of soluble star/ball shape polymers by adopting sequential living ring-opening metathesis polymerization (ROMP) of norbornene and cross-linking reagent (CL) using the molybdenum-alkylidene catalyst via a core-first approach. The approach also enables us introduction of functionalities at the polymer chain end (into the star-surface) exclusively: these exhibit unique characteristics as supported catalysts, fluorescent materials. We especially explored synthesis of these polymers with more side arms/branching, which should offer new carriers possible for providing more integration of functionalities. The synthesis has been achieved by increasing CL and/or conducting core formation in the co-presence of NBE; the resultant polymer possess high molecular weights with uniform distributions. The efforts should be applicable for synthesis of the desired materials (supported molecular catalysts) on the star polymer surface.
