摘要
综述了负载单中心催化剂用的镁铝载体的研究情况。主要介绍了镁铝载体的制备方法、组成、用途及特点。介绍了镁铝载体的激活能力、负载能力、能够负载的单中心催化剂种类以及负载催化剂的聚合行为,同时阐述了镁铝载体的形态特性。
The progress of aluminum complexes modified MgCl2-based support fo the immobilization of single-site catalysts in olefin polymerization is reviewed. Th preparation, components, utilization and features of this support are introduced. Th activating and supporting behavior of the support, and the supported single-site catalyst and their polymerization activities are demonstrated. The morphology of the support isdiscussed.
