Abstract:
The present invention relates to a transition metal complex represented by the formula (I): wherein M represents a Group 4 transition metal; —Y— represents (a): —C(R1)(R20)-A-, (b): —C(R1)(R20)-A1(R30)—, (c): —C(R1)=A1-, or (d): —C(R1)=A1-A2-R30; A represents a Group 16 element and A1 and A2 each represents a Group 15 element; R1 to R9, R20, and R30 are the same or different and each represents an optionally substituted hydrocarbon group, etc.; and X1 and X2 are the same or different and each represents a hydrogen atom, a halogen atom, an optionally substituted C1-10 alkyl group, etc., and an intermediate product thereof, and a catalyst for olefin polymerization which comprises said transition metal complex as a component.
