Outline of Final Research Achievements

We here proposed a novel synthetic route toward multicyclic polymers based on the consecutive cyclization of linear polymer precursors possessing a polymerizable group at each chain end. Specifically, the consecutive cyclization was achieved by the cyclopolymerization of macromonomers bearing a norbornenyl group at each chain end, affording multicyclic polymers with the targeted ring size and number of cyclic units. Furthermore, we have performed a systematic investigation of the correlation between the multicyclic architecture and physical properties.
