| titleOfInvention | Catalyst component for olefin polymerization, preparation method thereof, catalyst for olefin polymerization and olefin polymerization method |
| abstract | The invention relates to the field of olefin polymerization, and discloses a catalyst component for olefin polymerization, a preparation method thereof, a catalyst for olefin polymerization and an olefin polymerization method, wherein the preparation method comprises the following steps: the spherical carrier, the titanium compound, the silicon compound and the optional internal electron donor compound are subjected to contact reaction. The preparation method can avoid the crushing phenomenon of the spherical carrier in the preparation process of the catalyst component, thereby preparing the catalyst with good appearance, greatly improving the qualification rate of products, and simultaneously, the prepared catalyst has better catalytic activity and better economic benefit. |
