摘要
本文报道用ＡＰＴ、加驰豫试剂１３Ｃ－ＮＭＲ谱定量测定润滑油增粘剂氢化丁苯微观结构的结果，两种方法所得结果有较好的一致性，得到的有关结构信息丰富，是研究氢化丁苯微观结构较好的方法。
The hydrogenated butadiene-styrene copolymers were measured by using APT and relaxation reagent NMR spectra. The 13C resonance peaks of saturated carbons are assigned to individual carbon atoms in various diad or triad environment by APT, NMR spectra combined with calculated values using Lindeman's empirical parameters. The quantitative analysis results of microstructure of hydrogenated butadiene-styrene copolymers from relaxation reagent and APT methods conform with each other. The results from relaxation reagent method are in good agreement with the results from 1 H-NMR method.
