摘要: A catalyst component, which is to be combined with an organoaluminum component to form a Ziegler catalyst for olefin polymerization, is produced by treating (1) a solid composition resulting from a process of combining a magnesium halide such as magnesium chloride, an electron donor compound such as ethyl benzoate and a titanium halogen compound such as titanium tetrachloride with (2) an interhalogen compound or a halogen such as iodine trichloride.
