| abstract |
A catalyst component for olefin polymerization, prepared by bringing a titanium-containing solid which comprises (a) a metal oxide, (b) an organomagnesium compound represented by the following general formula: n nR¹MgR² n nwherein R¹ and R² each represents a hydrocarbon group containing from 1 to 20 carbon atoms, a halogen atom, or an OR³ group in which R³ represents a hydrocarbon group containing from 1 to 12 carbon atoms, provided that R¹ and R² do not represent a halogen atom at the same time, (c) an electron donor compound, and (d) a titanium compound having contacted with each other, into contact with (e) an α-olefin containing 3 carbon atoms or more in the presence of (f) an organoaluminum compound, to thereby contain a poly(α-olefin) in an amount of from 0.1 to 100 g per gram of said titanium-containing solid. |
