本文采用~13C-NMR方法研究了不同催化体系制备的聚丁二烯。经分析指出,聚丁二烯分子链的三种序列(顺-1,4-序列、反-1,4-序列和1,2-序列)和十七类脂碳碳核为~13C-NNR谱贡献了十六个谱峰。经数据的解析,得到一组计算聚丁二烯脂碳部分各谱峰化学位移的经验参数。在本文条件下,应用该组参数得到的计算值与实验值符合较好。本文确认了聚丁二烯反-1,4-序列第四峰(T_4)的存在。初步研究了聚丁二烯~13℃-NMR谱图的定量处理问题。 In this paper, 13C-NMR method was used to study the polybutadiene prepared by different catalytic systems. According to the analysis, the three sequences of polybutadiene chains (cis-1,4-trans, trans-1,4-and 1,2-sequences) The spectrum contributed sixteen peaks. After data analysis, a set of empirical parameters for calculating the chemical shifts of the peaks of the polybutadiene carbon moiety are obtained. Under the condition of this paper, the calculated values ​​obtained by using this set of parameters are in good agreement with the experimental ones. This article confirms the existence of the fourth peak (T_4) of the polybutadiene trans-1,4-series. The quantitative treatment of ~ 13 ℃ -NMR spectrum of polybutadiene was preliminary studied.
