Outline of Final Research Achievements

Analysis of cross-linking structures in rubbers by solid-state sulfur-33 Nuclear Magnetic Resonance (NMR) methodology is presented. We demonstrate that it is possible to obtain solid-state sulfur-33 NMR spectra of organosulfur molecules, forming mono-, di-, and poly-sulfide bonds, which work as model compounds of cross-linking structures in rubbers.

Academic Significance and Societal Importance of the Research Achievements

加硫ゴムは主に自動車用タイヤに使用されているが、タイヤの物性を決定する硫黄原子による架橋構造は未だに解明されていない。本研究では、アモルファス試料でも化学分析が可能な固体NMR法の活用を提案し、架橋構造解析の礎を築くことに成功した。従来の固体NMR装置では硫黄原子を直接観測することは困難であったが、報告者が開発した次世代型NMRシステムを活用することで、硫黄NMRスペクトルの観測と解析が可能であることを実証した。
