(57) [Summary] [Structure] ML 1 X (M is a transition metal, x is a valence, at least two ligands L 1 are a cyclopentadienyl group (Cp group), a methyl Cp group, and a carrier. , Cp having an ethyl Cp group or a group selected from a hydrocarbon group having 3 to 10 carbon atoms Group) and a ML 2 X (at least two ligands L 2 are substituted Cp groups having only 2 to 5 ligands selected from a methyl group and an ethyl group) An olefin polymerization catalyst obtained by prepolymerizing an olefin on a solid catalyst component carrying a transition metal compound and an organoaluminum oxy compound. An olefin polymerization method for polymerizing an olefin in the presence of the above-mentioned olefin polymerization catalyst. [Effect] An olefin polymer having excellent moldability, transparency and mechanical strength can be produced. |
