Process for preparing solid titanium catalyst component, olefin polymerization catalyst, and olefin polymerization process |
| abstract |
Disclosed is 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, a solid titanium catalyst component capable of polymerizing an olefin with high activity and capable of preparing an olefin polymer of high stereoregularity can be prepared. Also disclosed are an olefin polymerization catalyst containing a solid titanium catalyst component obtained by the above process and an olefin polymerization process using the olefin polymerization catalyst. |
