Outline of Final Research Achievements

We have found that magnesium bromide (MgBr2), which has never been reported as a catalyst for cationic polymerization, is useful as a Lewis acid catalyst for ring expansion cationic polymerization giving cyclic polymers effectively. We focused on the high oxophilicity of magnesium bromide and studied ring-expanding cationic polymerization in the presence of crown ether as an oxygen-based cyclic molecule, but no gelation happened.

Academic Significance and Societal Importance of the Research Achievements

近年,様々な特性を有する高分子ゲルが開発され,特性に応じて材料として使われ始めている。特に安全で環境に優しいモビリティ社会の実現に対し,高分子ゲル材料への期待は大きい。オリンピックゲルは,多くの高分子ゲル研究者が関心を抱きながら,これまで世界中で誰も合成したことが無いゲルである。今回オリンピックゲルの合成には至らなかったが,強力な環拡大重合系が見つかった意義は大きく,今後この環拡大重合系を用いて合成に至ることが期待される。
