文献上相继报导了一些对丁二烯聚合有高活性的铁系催化剂.这些催化剂组份中都含有给电子试剂作为配位体.最近我们开发了一类新型铁催化剂,它不含给电子试剂,而是用卤化物作为必要的第三组分.这一研究结果将对进一步了解铁系催化剂的活性中心本质提供有益的信息.
In the literature there have been reports of several iron-based catalysts which are highly active in the polymerization of butadiene, all of which contain an electron donating agent as a ligand.We recently developed a new class of iron catalysts which do not contain an electron donor , But using halide as an essential third component.The results of this study will provide useful information for further understanding of the nature of active sites in iron-based catalysts.
