Method for producing polyolefin |
| abstract |
(57) [Summary] [Structure] Using a catalyst comprising a transition metal compound having cyclopentadiene or a derivative thereof as a ligand, an organometallic compound, and a compound which reacts with the transition metal compound to form an ionic compound A method for producing a polyolefin, wherein a compound which reacts with a transition metal compound to form an ionic compound is added at least twice in a divided manner when the polyolefin is produced. [Effect] By using an inexpensively available catalyst component, it is possible to stably produce a polyolefin with high activity per catalyst. |
