采用带场梯度高速魔角自旋探针的固体核磁共振谱分析了硫化天然橡胶的交联结。通过一维和二维测量，包括逆相关测量，研究了硫化天然橡胶H-1和C-13的核磁共振光谱分辨率以及H-1和C-13之间的相关性。用固体核磁共振光谱法测定了交联节点上碳原子的取代数。爱思唯尔有限公司2009年版权所有版权所有。
Crosslinking junctions of vulcanized natural rubber were analyzed by solid-state NMR spectroscopy equipped with a field-gradient high speed magic angle spinning probe. Resolution of H-1 and C-13 NMR spectra and correlations between H-1 and C-13 of the vulcanized natural rubber were investigated by one- and two-dimensional measurements, including inverse correlation measurements. The number of substitution of the carbon atom at the crosslinking junctions was determined by solid-state NMR spectroscopy. Crown Copyright (C) 2009 Published by Elsevier Ltd. All rights reserved.
