| titleOfInvention | Process for preparing solid titanium catalyst component, olefin polymerization catalyst, and olefin polymerization process |
| abstract | This invention discloses a process for preparing a solid titanium catalyst component, comprising the steps of (I) contacting a liquid magnesium compound with a liquid titanium compound to precipitate a solid in the contact liquid (beta), and adding an electron donor (d-I) selected from the group consisting of a polycarboxylic ester and a polyether compound to the contact liquid (beta) during the time from beginning to end of the solid precipitation, to form a solid product (alpha); and (II) contacting the solid product (alpha) obtained after completion of the solid precipitation with an electron donor (d-ii) selected from the group consisting of a polycarboxylic ester and a polyether compound, to prepare a solid titanium catalyst component. According to the process, an olefin polymer of high stereoregularity can be prepared by using this catalyst in a polymerization process. This invention further discloses olefin polymerization catalyst containing the solid titanium catalyst composition obtained from the above-mentioned method and an olefin polymerization process using the olefin polymerization catalyst. |
