| 摘 要： | 本文采用Tonelli的γ-效应和Flory的聚丙烯旋转异构体模型,计算了无规聚丙烯~(13)C-NMR的不同立体异构中甲基碳的化学位移。计算值和观察值有很好的一致性。对文献上一些有争议的共振峰归属进行了讨论。

| Abstract: | The tonelli's r effect and Flory's rotational isomeric state model of polypropylene is employed to calculate the 13C-NMR chemical shifts of methyl carbon in the various ste-reoisomers of atactic polypropylene. The correspondence between calculated and observed chemical shifts difference is close. Some controversial assignments of resonance peaks in literature are discussed. |
