Abstract: 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-ethanols complex 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.

Abstract: Disclosed are a universal alpha-olefin polymerization industrial catalyst, and an application thereof, specifically an industrial production catalyst which consists of (A) a solid catalyst component, (B) a cocatalyst organoaluminium compound and (C) an external electron donor compound, and is used for various alpha-olefin polymerization or copolymerization processes. The solid catalyst component (A) is prepared from a dibutyl phthalate or diisobutyl phthalate and 9,9-bis(methoxymethyl)fluorene composite internal electron donor. A hydrocarbyl alkoxy silicon, an organic acid ester or a hydrocarbyl alkoxy silicon and organic acid ester composite acts as the external electron donor component (C). The solid catalyst component (A), the cocatalyst organoaluminium compound (B) and the external electron donor compound (C) are used together in industrial devices for various alpha-olefin polymerization or copolymerization processes to produce new grades of poly-alpha-olefins.

Abstract: Disclosed are a Z-N catalyst for α-olefin polymerization and an application thereof, specifically, an industrial production catalyst consisting of (A) a solid catalyst component, (B) a cocatalyst organoaluminum compound and (C) an external electron donor compound and used for α-olefin polymerization or copolymerization processes. The catalyst component is prepared from a transition metal such as titanium and magnesium and a composite aromatic diacid diester/1,3-diether as an internal electron donor. One or more organoaluminum compounds or a mixture thereof serve as the cocatalyst. One or more structure control agent hydrocarbyl alkoxysilicons are compounded with one or more activity regulator organic acid esters as the external electron donor capable of automatically adjusting the polymerization rate. The Z-N catalyst is used for α-olefin polymerization/copolymerization, and can automatically adjust the polymerization rate at a higher polymerization temperature so as to maintain stable operation of a reactor.
