Transition metal compound, olefin polymerization catalyst, and olefin polymer production process

摘要

[Object] To provide transition metal compounds with excellent catalytic activity which can afford olefin polymers such as propylene polymers that have high stereoregularity and high molecular weight and may be easily crystallized into a β-phase.;[Solution] The transition metal compound is represented by General Formula [I] or is enantiomer thereof:;[in Formula [I], R1, R3, R5, R6, R7, R8, R9, R10, R11, R12, R13, R14, R15 and R16 are each independently a hydrogen atom, a hydrocarbon group, a heteroatom-containing hydrocarbon group, or a silicon-containing group; R2 is a hydrocarbon group, a hetero atom-containing hydrocarbon group, or a silicon-containing group; R4 is a hydrogen atom; any two substituents of the substituents R1 to R16 except R4 may be bonded to each other to form a ring; M is a Group IV transition metal; Q is a structure such as a halogen atom; and j is an integer of 1 to 4].
