摘要
本文采用ASED-MO法对Ziegler-Natta型催化剂催化的α-烯烃聚合过程中AlR_3组分对催化剂活性的影响进行了研究.得到了无AlR_3组分存在和一系列不同AlR_3存在时链增长过程的能量变化和相应的活化能.通过比较看出,AlR_3存在可以明显增强催化剂活性.同时运用分子轨道分析的方法探讨了AlR_3增强催化活性的原因.
The effect of AIR3 on the catalytical activity in Ziegler-Natta type polymerization of α-olefine with ASED-MO method was studied. Changes in energy and related activation energies in the process of chain growths with and without the presence of AlR3 were obtained. It ii shown that AlR3 enhances the activity of the catalyst remarkably. The function of AlR3 was discussed theoretically in terms of ASED-MO method.
