Abstract:
An olefin polymerization catalyst comprising (A) a transition metal compound represented by the following formula (I): wherein M is a transition metal atom selected from the group consisting of Group 3 to Group 5, Group 7 to Group 9 and Group 11 of the periodic table,U1 is a carbon atom having a substituent group R2, a nitrogen atom or a phosphorous atom, A is a nitrogen atom or a phosphorous atom, Q is a carbon atom having a substituent group R3, a nitrogen atom or a phosphorous atom, S1 is a carbon atom having a substituent group R4, a nitrogen atom or a phosphorous atom, T is a carbon atom having a substituent group R5, a nitrogen atom or a phosphorous atom, m is an integer of 2 to 6, R1 to R5 may be the same or different, R1 to R5 are each a hydrogen atom, a halogen atom, a hydrocarbon group, a heterocyclic compound residual group, an oxygen-containing group, a nitrogen-containing group, a boron-containing group, a sulfur-containing group, a phosphorous-containing group, a silicon-containing group, a germanium-containing group or a tin-containing group; two or more of R1 to R5 may be bonded to each other to form a ring, and one group of R1 to R5 contained in one ligand and one group of R1 to R5 contained in another ligand may form a bridging group or a single bond, wherein when one group of R1 in one ligand and one group of R1 contained in another ligand form a bridging group, the bridging group is a hydrocarbon group having 3 or more carbons atoms; n is a number satisfying the valence of M, and X is a hydrogen atom, a halogen atom, a hydrocarbon group, an oxygen-containing group, a sulfur-containing group, a nitrogen-containing group, a boron-containing group, an aluminum-containing group, a phosphorous-containing group, a halogen-containing group, a heterocyclic compound residual group, a silicon-containing group, a germanium-containing group or a tin-containing group and when n is 2 or greater, plural groups indicated by X may be the same or different to each other and plural groups indicated by X may be bonded to each other to form a ring.
