BOPP微观等规度的研究

Study on Microisotacticity of BOPP

用13C-NMR(核磁共振)和DSC(差热分析)方法分析了燕山石化股份有限公司生产的BOPP均聚物,并对其微观等规度进行了研究,发现可以用外给电子体对BOPP的微观等规度进行调控,从而使BOPP树脂的拉膜质量显著提高,达到国外进口BOPP树脂的水平。

The microisotacticity of BOPP has been studied by 13C-NMR and DSC. It was found that the quality of BOPP could be improved by regulating microisotacticity of BOPP。
