Internal electron donor compound for preparing α-olefin polymerization catalyst component
An internal electron donor compound for preparing α-olefin polymerization catalyst component, including two kinds of electron donors; the proportion of the two kinds of electron donors in the compounding preparation of the catalyst is determined via designed experiments so as to obtain a catalyst component having good comprehensive performance or a particular performance. The electron donor compound of the present invention can be used in the preparation of α-olefin polymerization and co-polymerization catalyst component, particular the preparation of propylene polymerization catalyst component, and is applicable to prepare the propylene polymerization catalyst component by reacting magnesium chloride-ethanolscomlex compound carrier with titanium tetrachloride and electron donors, or to directly prepare the propylene polymerization catalyst component by reacting magnesium chloride, alcohols, titanium tetrachloride, and internal electron donor. In addition, also provided is a theoretical basis for selecting a proper electron donor combination from a plurality of electron donors.
