| titleOfInvention | Olefin polymerization catalyst and preparation method thereof and olefin polymerization method |
| abstract | The invention provides an olefin polymerization catalyst, which contains titanium, silicon, magnesium, phosphorus, an internal donor compound and halogen. The invention further provides a method for preparing the olefin polymerization catalyst disclosed by the invention. The invention further provides an olefin polymerization method. Silicon is introduced into the olefin polymerization catalyst, so that the catalytic activity of the olefin polymerization catalyst for olefin polymerization is 1.1-1.5 times higher than that of a catalyst into which silicon is not introduced in the prior art. According to the method for preparing the olefin polymerization catalyst disclosed by the invention, a silane compound is introduced in the contacting process of a magnesium compound, an organic epoxy compound and an organic phosphorus compound in a solvent, so that the activity of the prepared catalyst is much higher than that of a catalyst obtained with a method in which a silane compound is not introduced in the prior art. The method disclosed by the invention has the advantages of readily-available raw materials and low production cost. |
