Outline of Final Research Achievements

We conducted research to develop a polymerization method that combines reversible addition-fragmentation chain transfer polymerization (RAFT) polymerization with a morphology control factor (ring-expansion RAFT polymerization) as a technology that leads to the creation of highly functional materials. The structure of the product produced by the ring-expansion RAFT polymerization was clearly shown for the first time by atomic force microscopy (AFM) observation. The introduction of cyclic morphology into the recent advanced synthesis technique, "photo-induced electron transfer-RAFT (PET-RAFT) polymerization," was also carried out, and new knowledge about the polymerization system was obtained from the structural analysis of the products.

Academic Significance and Societal Importance of the Research Achievements

有機ガラスの主成分でもあるポリメチルメタクリレートなどの「汎用のビニルポリマー」に高付加価値を付与する手段として「精密重合」に「モルフォロジー制御因子」を相乗した「環拡大ビニル重合」の開発について研究を実施した。顕微鏡観察を含めた重合生成物の構造解析などから、学術および科学の進歩に貢献する新たな知見を得た。新奇な高機能素材をもたらす活用範囲の広い技術の創出に繋がる成果が得られたと考えている。
