| titleOfInvention | Method for preparing Ziegler-Natta catalyst for olefin polymerization and method for producing polypropylene using this catalyst |
| abstract | The present invention relates to a method for preparing an olefin polymerization catalyst and a method for producing polypropylene using the catalyst. The method for preparing a catalyst of the present invention comprises a compound having two or more ether functional groups as an internal electron donor, magnesium dichloride, organic Characterized in that it is prepared by a conventional method using an alcohol, an organophosphorus compound as a starting material, the method for producing a polypropylene of the present invention is a Ziegler-Natta catalyst prepared by the above method and the organic aluminum compound as a cocatalyst It is characterized by using an external electron donor having at least one silicon ether bond. According to the present invention, it is possible to prepare a catalyst using a small amount of titanium compound while maintaining high activity and high stereoregularity, and by using the catalyst, a polyolefin having a large particle size can be prepared. |
