用红外光谱法测定聚丙烯等规度已经许多年了。但是,某些作者所选择的一些定量谱带的物理意义不同,所获得的结果彼此无法比较。根据我们的实验也证明了有些报导中选择的定量谱带和内标谱带是不恰当的,测定的结果误差太大。因此,在应用红外光谱测定聚丙烯等规度中,多年来遇到了不少困难。本工作期望能够比较合理地选择谱带,正确地理解用红外光谱法测定的等规度的物理意义,以便能够独立地将红外光谱法快速准确地应用于聚丙烯等规度
It has been many years since the isotacticity of polypropylene has been determined by infrared spectroscopy. However, some authors selected some of the quantitative bands to have different physical meanings and the results obtained were not comparable to each other. According to our experiments, it was also proved inappropriate to select the quantitative bands and internal standard bands in some reports, and the results of the determination were too large. As a result, many difficulties have been encountered over the years in the application of IR spectroscopy to the determination of polypropylene. This work is expected to be able to select the band more rationally and correctly understand the physical meaning of the isotacticity measured by infrared spectroscopy in order to be able to independently and quickly apply infrared spectroscopy to polypropylene isotactic
