<p>A catalyst which comprises a compound of a transition metal in Groups 8 to 10 of the Periodic Table having a nitrogenous tridentate ligand, a clay, clay mineral, or lamellar ion-exchanging compound, an organosilane compound, an organoaluminum compound, etc.; and a process for producing a polyolefin with the catalyst. The catalyst is highly active, does not adhere to reactor walls, and can give a polyolefin excellent in powder morphology. Consequently, a polyolefin (especially polyethylene) can be industrially advantageously produced.</p> |
