| Outline of Final Research Achievements |
This study aimed to construct the highly precise polymerization system consisting of living polymerization, concurrent copolymerization via different mechanisms, and sequence-controlled polymerization. Design strategies to realizing the three elements were devised on the basis of the following three topics: (1) the concurrent cationic vinyl-addition and ring-opening copolymerization of vinyl ether and oxirane mediated by long-lived species, (2) the concurrent cationic vinyl addition, ring-opening, and carbonyl-addition terpolymerization of vinyl ether, oxirane, and ketone toward the ABC-type alternating sequence control, and (3) the multiblock polymer synthesis through the long-lived species-mediated cationic terpolymerization of vinyl ether, oxetane, and ketone.
