Patent ID: 8372996

Claim:
A transition metal compound represented by Chemical Formula (1): wherein, M represents transition metal from Group 4 in the Periodic Table of Elements; Cp represents a cyclopentadienyl ring which is η 5 -linkable to M, or a fused ring containing a cyclopentadienyl ring, in which the cyclopentadienyl ring or the fused ring containing a cyclopentadienyl ring is optionally further substituted by (C1-C20)alkyl, (C6-C30)aryl, (C2-C20)alkenyl or (C6-C30)ar(C1-C20)alkyl; Ar represents (C6-C30)aryl, but Ar is not fluorenyl; X 1 and X 2 are independently selected from a group consisting of halogen atoms, (C1-C20)alkyl, (C3-C20)cycloalkyl, (C6-C13)aryl, (C1-C10)alkyl(C6-C13)aryl, (C6-C30)ar(C1-C20)alkyl, (C1-C20)alkoxy, (C3-C20)alkylsiloxy, (C1-C20)alkylamino, (C6-C30)arylamino, (C1-C20)alkylphosphine, (C6-C30)arylphosphine, (C1-C20)alkylmercapto and (C6-C30)arylmercapto; m is an integer selected from 0 to 4, n is an integer from 0 to 2; R represents (C1-C10)alkyl, (C3-C10)cycloalkyl, (C6-C13)aryl, (C1-C10)alkyl(C6-C13)aryl, (C6-C13)ar(C1-C10)alkyl or (C1-C10)alkoxy, and the alkyl, cycloalkyl, alkylaryl, aralkyl, alkoxy, alkylsiloxy, alkylamino, arylamino, alkylphosphine, arylphosphine, alkylmercapto, arylmercapto of X 1 and X 2 ; the alkyl, cycloalkyl, aryl, alkylaryl, aralkyl, alkoxy of R; and the aryl of Ar are optionally further substituted by one or more substituent(s) selected from a group consisting of (C1-C10)alkyl, (C3-C10)cycloalkyl, (C6-C13)aryl, (C1-C10)alkyl(C6-C13)aryl, (C6-C13)ar(C1-C10)alkyl and (C1-C10)alkoxy, or each of them is optionally linked to an adjacent substituent via (C3-C12)alkylene or (C3-C12)alkenylene with or without a fused ring to form an alicyclic ring, or a monocyclic or polycyclic aromatic ring.
