在用红外偏振光谱测定聚丙烯薄膜取向,及用示差偏振红外光谱分离聚丙烯非谱带的基础上,进一步研究了用红外偏振光谱及及示差偏振光谱测定聚丙烯纤维晶区、菲晶区、及整个分子链的取向;并和其他方法配合,利用实验数据对聚丙烯某些频率的跃迁矩角度进行了计算,所得结果与文献值基本一致,给理论探讨创造了一定的有利条件。
The orientation of polypropylene film was measured by infrared polarization spectroscopy and the non-band separation of polypropylene was analyzed by differential polarization infrared spectroscopy. The further study on the determination of polypropylene fiber crystal zone and phenanthrene crystal zone by infrared polarization spectroscopy and differential polarization spectroscopy, And the orientation of the whole molecular chain. And with other methods, the experimental data were used to calculate the transition moments of polypropylene at some frequencies. The obtained results are in good agreement with the literature values, which has created some favorable conditions for the theoretical study.
