Outline of Final Research Achievements

In this study, movable cross-linking points were introduced to common polymers to fabricate rotaxane cross-linked polymers (RCPs) using rotaxane-based crosslinkers containing vinyl and nitrile N-oxide groups. In addition, it was revealed that highly movable rotaxane structure were effective when it was introduced in segmented polyurethane network structures.

Academic Significance and Societal Importance of the Research Achievements

本研究は従来まではマトリックスポリマーに制限のあったロタキサン架橋高分子のデザイン性を大きく広げるものである。またロタキサンの特徴的な動的特性を活用した分解性架橋高分子の合成や触媒や溶媒を用いない架橋体合成にも成功していることから、サステイナブルな高強度スマートマテリアルの創成に繋がるものである。
