According to the contribution of main structural units to the peaks, six equations for diad concentrations in terms of peak intensity have been derived based on the ~(13)C-NMR spectrum assignments of hydrogenated styrene-butadiene copolymers (HPBS).

• 在氢化丁苯共聚物~(13)C-NMR谱脂肪碳部分谱带归属的基础上,根据各谱带的主要来源,推导出六个二单元浓度的计算公式。
