| titleOfInvention | Catalyst system for olefin polymerization and application thereof |
| abstract | The invention provides a catalyst system for ethylene polymerization, which comprises the following components: component a. a titanium-containing solid catalyst component prepared by: dissolving magnesium halide in a solvent system containing an organic alcohol compound to form a solution, adding an organic silicon compound without active hydrogen to obtain a mixed solution, then carrying out a titanium carrying process by contacting and reacting the mixed solution with a titanium compound, optionally adding or not adding the organic silicon compound without active hydrogen for reaction, stirring and washing; component b. an organoaluminum compound, component c. a halogenated cycloalkane compound, and component d. a halogenated metal compound. The catalyst system of the invention is used for ethylene polymerization, not only shows higher catalytic activity, but also shows higher hydrogen regulation sensitivity, and is suitable for producing polyethylene with wide molecular weight distribution and high melting index. |
