Outline of Final Research Achievements

A study to develop the polymerization system that enables "ring-expansion vinyl polymerization" has been demonstrated. The polymerization products were transformed into polymer brushes and then observed by the atomic force microscopy (AFM). This process showed the ring-expansion polymerization system truly produced polymers with cyclic morphology. Additional molecular chain analyses based on the chromatographic and spectroscopic methodologies provided crucial insights into the mechanisms for the ring-expansion vinyl polymerization system.

Academic Significance and Societal Importance of the Research Achievements

1990年代から、精密高分子合成法としてリビングラジカル重合 (制御ラジカル重合) が加わり、ビニルポリマーの特殊構造化・多様化が進められてきた。しかし、ビニルモノマーの環拡大重合に関してはその開発が世界的に特に遅延している。本研究では、顕微鏡による分子鎖の観察と解析・統計を併せ、学術的に有意義な重要な知見を得た。材料の軽量化・高強度化を達成する手段として、ポリマーへの環状モルフォロジーの導入は産業界でも注視されており、本研究の成果は社会的にも有意義である。
