摘要
用FT-IR法研究了四氯乙烷在烯烃聚合催化剂体系中的作用。结果表明,由于四氯乙烷的加入使催化剂中甲基吡咯和三乙基铝的氢键打开形成各自游离态分子,消除由于氢键所造成的分子间作用力和空间位阻,有利于组分间配位。
Effect of cellon existing in the catalyst system on olefin polymerization was examined by Fourier transform infrared spectroscopy (FT-IR).The results showed that cellon in the system caused the hydrogen bonds of methyl pyrrole and triethyl aluminum in the system to break into the corresponding unbound states,thereby eliminating the intermolecular forces and spatial hindrance formed by hydrogen bonds,and thus facilitating coordination between the components.
