| titleOfInvention | Ziegler-Natta catalyst for olefin polymerization and preparation method thereof |
| abstract | The present invention relates to a method for preparing a Ziegler-Natta catalyst for olefin polymerization having high activity, high stereoregularity and low fine content. Specifically, (a) anhydrous magnesium dichloride is dissolved in anhydrous alcohol and a hydrocarbon solvent, and then Adding a precipitation promoter to the reaction to prepare a magnesium carrier mixed solution; (b) putting the magnesium carrier mixed solution into a transition metal compound to obtain a precipitate; (c) adding a potential metal to react with each other to obtain a compound, and then washing the compound with a hydrocarbon solvent to obtain a solid catalyst; (d) The internal electron donor is a carboxylic acid anhydride, which is added to the Ziegler-Natta catalyst for olefin polymerization comprising the step of adding in any one or more of steps (a) or (c) of the catalyst manufacturing process. It relates to a manufacturing method. |
