TextPublication details: Kautschuk Gummi Kunststoffe 2013Description: 28-33Subject(s): Summary: Field gradient-fast-magic angle spinning (FG-FMAS) probe, developed for solid-state NMR spectroscopy, was applied to investigate crosslinking junctions of vulcanized natural rubber. Resolution of 1H-and 13C-NMR spectra and correlation between 1H 13C of the vulcanized natural rubber were investigated. signals, appearing between 40 and 60 ppm, were well assigned by FG-FMAS-NMR spectroscopy. Based on the assignments of the signals, origin of outstanding mechanical prperties of the vulcanized natural rubber was found to be due partly to the structure of crosslinking junctions.
