Solid catalyst component for polymerization of ethylene, preparation thereof and a catalyst containing the same
摘要:
The present invention provides a catalyst component used for homopolymerization or co-polymerization of ethylene, comprising at least one suitable electron donor compound supported on a composition containing magnesium and titanium, wherein the electron donor compound is selected from the group consisting of aliphatic ethers, alicyclic ethers, aromatic ethers, aliphatic ketones and alicyclic ketones, and wherein the composition containing magnesium and titanium is prepared by dissolving a magnesium compound into a solvent system to form a homogeneous solution and then contacting the solution with a titanium compound in the presence of a precipitation aid to precipitate the composition. The present invention also relates to a method for the preparation of said catalyst component and a catalyst comprising thereof, and to use of the catalyst in homopolymerization of ethylene or co-polymerization of ethylene with at least one C3–C8 α-olefin.
