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.
