| titleOfInvention | The Manufacturing Method Of Photo Catalyst For Olefine Polymerization |
| abstract | The present invention relates to a method for preparing an olefin polymerization catalyst and a method for producing polypropylene using the catalyst, wherein the method for preparing a catalyst according to the present invention is a nonionic surfactant containing magnesium dichloride dissolved in a mixed solution of an organic alcohol and an aromatic hydrocarbon. And the mineral oil and the active ingredient are suspended in a mixed solution of titanium tetrachloride and prepared as a starting material by a conventional method. The method for preparing polypropylene of the present invention is the Ziegler-Natta prepared by the above method. An organoaluminum compound is used as a catalyst and a cocatalyst, and an organosilicon, an ether or an ester compound is used as an external electron donor. According to the present invention, it is possible to prepare a catalyst which maintains high activity and high stereoregularity and exhibits an excellent particle size of the polymer, and has an advantage of not excessively using titanium tetrachloride in the preparation step. |
