| 摘 要： | 本文研究了在不同pH条件下P(AM/AA)溶液的13C-NMR谱,观察了谱峰的化学位移变化和分裂情况,对比了均聚物PAM和PAA的13C-NMR谱,对P(AM/AA)13C-NMR谱的各共振峰进行了归属,证实P(AM/AA)共聚物C=O碳峰的分裂只与分子链共聚序列结构相关,并得出了C=O碳分裂峰所对应的三单元序列结构。

| Abstract: | The structures of P(AM/AA) copolymers were determined from 13C-NMR spectra. Based on the observation and comparison of chemical shifts between homopolymers PAM、PAA and copolymers P(AM/AA), the assignments of the spectral lines of P(AM/AA) were established. The split peaks of carbonyl carbons in P(AM/AA) were related to the contribution of triad copolymeric sequence distribution in the molecular chains. |
