Ziegler-Natta catalysts for olefin polymerization |
| abstract |
The present invention relates to a Ziegler-Natta catalyst for olefin polymerization having high activity and low fine powder. In the manufacturing process, firstly, anhydrous magnesium dichloride is dissolved in anhydrous alcohol and a hydrocarbon solvent, and then a precipitation accelerator is added thereto to react. To prepare a magnesium carrier mixed solution; Secondly, putting the magnesium carrier mixed solution into a transition metal compound to obtain a precipitate; Third, adding a potential metal and an internal electron donor to react to obtain a compound, and then washing the compound with a hydrocarbon solvent to obtain a solid catalyst; Fourth, the internal electron donor is bisthioacyl sulfide (Bis) for olefin polymerization prepared by a method comprising the step of adding at least one of (a) or (c) step of the catalyst manufacturing process. Relates to a Ziegler-Natta catalyst. |
