Abstract of the Disclosure A catalyst composition for the polymerization or copolymerization of olefins composed of (A) a titanium component (a-1) or (a-2), (a-1) a highly active titanium component containing titanium, magnesium and halogen as essential ingredients, or (a-2) a highly active titanium catalyst component obtained by treating component (a-1) with an organic compound containing active hydrogen bonded to oxygen, and (B) an organoaluminum compound component, wherein (i) when component (A) is the component (a-1), component (B) is an organoaluminum compound component obtained by treating a halogen-containing organo- aluminum compound having a halogen/A1 atomic ratio of at least 1 but less than 2 with a compound selected from the group consisting of water and organic compounds having active hydrogen bonded to oxygen, and (ii) when component (A) is the component (a-2), the component (B) is a halogen-containing organoaluminum compound having a halogen/A1 atomic ratio of at least 1 but less than 2, and the ratio of the amount (x) of the organic compound having active hydrogen atom bonded to oxygen and/or an oxygen- containing group derived from said organic compound to the amount (y) of titanium, x:y, is 4-100:1.
