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.
Claims4
A chelate catalyst in the liquid state for olefin polymerization, prepared by the steps of:
- producing magnesium compound containing chelate ligand by reacting imidazole chelate ligand with the compound of the form of Mg[Al(OR)3R′]2 (R and R′ stand for alkyl group);
- producing titanium compound in the liquid state by reacting said magnesium compound with titanium halide compound;
- and
- preparing the catalyst by reacting said titanium compound in the liquid state with Mg[Al(OR)3R′]2 again.
