CATALYST FOR OLEFIN POLYMERIZATION AND PROCESS FOR PRODUCING OLEFIN POLYMER WITH THE CATALYST

摘要

A catalyst which comprises a compound of a transition metal in Groups 8 to 10 of the Periodic Table having a nitrogenous tridentate ligand and an organoaluminum compound such as trimethylaluminum; and a process for producing a polyolefin with the catalyst. The catalyst is highly active and enables a high-molecular polyolefin to be produced. Consequently, a high-molecular polyolefin (especially polyethylene) suitable for practical use can be industrially advantageously produced without using methylaluminoxane, which is expensive, has poor handleability and poor storage stability, and is highly dangerous.
