Transition metal compounds of the general formula (I), and polymerization catalysts for olefins containing the compounds and activating promoters as the main components. In said formula M is a metal element selected from among Group 3 to 10 metal elements of the periodic table and lanthanoids; X is a s-bonding ligand bonded to M; Y is a Lewis base; A is a bridge group; p is an integer of 1 to 20; q is an integer of 1 to 5 satisfying the relationship: [(the valency of M) - 2]; r is an integer of 0 to 3; R2 to R9are each hydrogen, halogeno, hydrocarbyl, halogenated hydrocarbyl, a silicon-containing group, or a heteroatom-containing group; and R1 is a group selected from among those defined for R2 to R9 except hydrogen). Thus, the invention provides transition metal compounds useful as catalytic components for the polymerization of olefins and polymerization catalysts for olefins containing the compounds. |
