| titleOfInvention | Catalyst component for olefin polymerization and catalyst thereof |
| abstract | The invention discloses a catalyst component for olefin polymerization, which is prepared by a method comprising the following steps: 1) mixing a magnesium compound with an organic alcohol compound and an inert solvent, and adding a compound shown in a structural general formula I for treatment to obtain an alcohol compound; 2) contacting the alcohol compound with a titanium compound at low temperature, adding an internal electron donor compound for reaction, and separating solid particles; 3) adding the solid particles obtained in the step 2) into a titanium compound solution, stirring and reacting, and separating solid particles; 4) washing the solid particles obtained in step 3) with an inert solvent to obtain the catalyst component; the catalyst component of the invention is used for olefin polymerization, has higher activity and adjustable orientation capability, good hydrogen regulation sensitivity of the catalyst, and wider molecular weight distribution of the prepared polymer. |
