    摘要: PROBLEM TO BE SOLVED: To provide an olefin polymerization catalyst which has high polymerization activity and excellent copolymerization activity with α-olefins and gives high molecular weight polymers. SOLUTION: This olefin polymerization catalyst comprises a transition metal compound represented by the general formula (I) [M is a group 4 or 5 transition metal atom in the periodic table; (m) is an integer of 1 or 2; R 1 is an aliphatic or alicyclic hydrocarbon group; R 2 to R 5 are each a hydrocarbon group, H, a hydrocarbon-substituted silyl group, an oxygen-containing group, a nitrogen-containing group, or a sulfur-containing group; R 6 is an aliphatic hydrocarbon group whose carbon directly bound to the phenyl group is a primary, secondary or tertiary carbon, an alicyclic hydrocarbon group whose carbon directly bound to the phenyl group is a tertiary carbon, or an aromatic group; (n) is the number satisfying the valency of M; X is selected from H, halogen atoms, hydrocarbon groups, heteroatom-containing groups, and the like].
