摘要:
The present invention provides a metallocene compound which produces an olefin polymer having a high molecular weight with a high stereoregularity. The metallocene compound has the following formula (1): Q(C5H4-mR1m)(C5H4-nR2n)MXY (1) wherein (C5H4-mR1m) and (C5H4-nR2n) each independently represent a cyclopentadienyl group; C5H4-m and C5H4-n each independently represent a cyclopentadienyl ring; m represents an integer of 1-3; n represents an integer of 2 or 3; R1 and R2 are each independently a substituent bonded respectively to C5H4-m and C5H4-n, and represent a hydrocarbon group of 1-20 carbon atoms, a silicon-containing hydrocarbon group of 1-20 carbon atoms or a heteroaromatic group; each R1m and each R2n may be the same or different; one pair of R2's in the R2n are bonded to each other to form at least one ring; Q represents a divalent group for cross-linking (C5H4-mR1m) and (C5H4-nR2n); M represents a titanium atom, a zirconium atom or a hafnium atom; and X and Y are the same or different and each a hydrogen atom, a halogen atom or a hydrocarbon group.
