摘要：
A Group VIB metal-based, ligand-containing olefin polymerization catalyst component can be made by using Group VIB metal trihalide as the starting reagent for the Group VIB metal which process comprises contacting (e.g., in tetrahydrofuran) the Group VIB metal trihalide, such as chromium trichloride, with the ligand reagent or reagents, such as a cyclopentadienyl-containing lithium compound and a lower alkyl-containing lithium compound, in the presence of a sigma donor stabilizing ligand, such as pyridine.
