自 Silas 和 Kimmer 提出可不用高纯标样的红外光谱分析方法后,这种方法被广泛地应用于聚丁二烯橡胶微结构的分析,但在聚丁二烯橡胶的分析中,由于顺式-1,4谱带在650—880cm~(-1)区,随含量的变化可出现675、738和775cm~(-1)三个谱带,这些谱带依赖于相邻单元的构型,与链结构的变化有关。由于这种顺式谱带的多变性,导致了聚丁二烯构型含量分析误差。为此不同作者采用不同的顺式-1,4谱带作为分析带。聚丁二烯构型含量分析误差在顺式含量低用薄膜进行测量时表现得尤为突出。本工作结合高-1,2聚丁二
Since Silas and Kimmer proposed the infrared spectral analysis method without using high purity standard samples, this method has been widely used in the analysis of microstructures of polybutadiene rubber. However, in the analysis of polybutadiene rubber, cis-1 There are three bands of 675, 738 and 775 cm -1 in the region of 650-880 cm -1. The bands depend on the configuration of adjacent units, Structure changes related. Due to the variability of this cis-band, the error of polybutadiene configuration analysis results. Different authors used different cis-1,4 bands for analysis. The polybutadiene configurational content analysis error is particularly pronounced when the cis content is measured with a thin film. This work combined with high -1.2 poly two
