ABSTRACT:
The present invention provides a novel chelated catalyst for olefin polymerization and an olefin polymerization method using the chelated catalyst. The catalyst of the invention is a liquid titanium compound chelated with an imidazole ligand. The method for olefin polymerization of the present invention is performed using the liquid titanium compound as a main catalyst component.
