摘要：A transition metal complex of the following formula (1): in which A represents an atom of Group 16 of the periodic table; B1 represents an atom of Group 14 of the periodic table; M1 represents a transition metal atom of Group 4 of the periodic table; Cp1 represents a group having a cyclopentadiene anion backbone; R1, R2, R3, R4, R5 and R6 represent independently of one another a hydrogen atom, a halogen atom, a C1-20 alkyl group optionally substituted with a halogen atom; R7, R8, R9, R10, R11 and R12 represent independently of one another a hydrogen atom, a C1-20 alkyl group optionally substituted with a halogen atom; and a 1,3-diene comprising R7, R8, R9, R10, R11, R12 and 4 carbon atoms coordinates on M1, and the 1,3-diene may be of either a cis or trans form, or a mixed form thereof, although the coordination form is not limited, and the double bonds may be delocalized. When this transition metal complex is used as a catalytic component, high molecular weight polyolefin is produced with high catalytic activity.
