Abstract

The invention relates to the field of olefin polymerization, and specifically provides a catalyst component used for olefin polymerization and a preparation method and application thereof. The preparation method comprises a step of subjecting a magnesium halide adduct, a titanium compound and an aromatic carboxylate compound to a contact reaction. The magnesium halide adduct is prepared through the following steps: (1) mixing aquo MgX1Y, R1OH and an alkoxy benzoyl compound and heating the obtained mixture so as to obtain a liquid magnesium halide adduct, or mixing anhydrous MgX1Y, R1OH, the alkoxy benzoyl compound and water and heating the obtained mixture so as to obtain the liquid magnesium halide adduct; and (2) allowing the liquid magnesium halide adduct to penetrate through a structural unit with holes to a liquid cooling medium under the action of pressure in the presence of an inert liquid medium, and carrying out quenching formation and drying. The invention provides a catalyst system used for olefin polymerization and application thereof, and an olefin polymerization method. The catalyst component synthesized from an adduct carrier prepared by using the method has improved hydrogen sensitivity when used for olefin polymerization.

Description

technical field

[0001] The present invention relates to a method for preparing a catalyst component for olefin polymerization, and the catalyst component for olefin polymerization obtained by the method and its application in the preparation of a catalyst system for olefin polymerization; and for olefin A catalyst for polymerization and its use in olefin polymerization; and an olefin polymerization method using the catalyst for olefin polymerization of the present invention. technical background

[0002] It is known in the prior art to support titanium compounds and electron donor compounds on active magnesium halides to prepare Ziegler-Natta catalysts. Among them, the active magnesium halide often uses the adduct of magnesium halide and alcohol, which is used as a carrier to react with titanium halide and electron donor compound to obtain a spherical catalyst. The spherical catalyst is used in olefins (especially propylene) During polymerization, it has higher polymerizati...
