摘要: 研究了红外3100~2800cm-1谱区的聚丁二烯图谱,它是聚丁二烯的顺-1,4,反-1,4和1,2微观结构信息叠加谱区。用因素分析技术对聚丁二烯的微观结构进行了定量分析,与传统的分析方法和其它谱区的因素分析进行比较,结果显示3100~2800cm-1港区的因素分析为现用方法中最佳。

Abstract: The infrared spectra of polybutadiene in the region from 3100 to 2800 cm-1 have been investigated.The spectra give reliable information related to the microstructure of polybutadiene, i.e cis-1, 4 trans-1,4 and1,2. The microstructure of polybutadiene samples has been determined by factor analysis of IR spectra in the region from 3100 to 2800 cm-1 as well as from 1000 to 650 cm-1. The scectra from the first region were proved more reasonable for the microstructure determination in comparison with those usedin the traditional IR analysis.
