摘要
用 DEPT NMR 测定了氢化丁苯共聚物,采用 Lindeman 经验参数计算其二单元、三单元不同单体序列分布中饱和碳部分各碳原子在^(13)C-NMR 谱中的化学位移值。DEPT 实验结果与经验参数计算值相结合,确定了氢化丁苯^(13)C-NMR 谱的归属。利用 DEPT 谱计算了氢化丁苯中各微观结构含量,结合400MHZ ~1H-NMR 信息,全面地表征了氢化丁苯链结构。
Hydrogenated butadiene-styrene copolymers were measured with DEPT NMR
spectra.The ^(13)C resonance peaks of saturated carbons are assigned to individual
carbon atoms in various diad or triad environment by empirical parameters.The
chain structure of hydrogenated butadiene-styrene copolymer are characterized
by DEPT NMR spectra and 400 MH(?) ~1H-NMR spectra.
