Claim:
A catalyst composition comprising: a transition metal complex represented by Formula 1 below; and at least one cocatalyst compound selected from the group consisting of compounds represented by Formulae 5, 6, and 7 below: where, CY1 is a portion of a substituted or unsubstituted aliphatic or aromatic ring, M is a Group 4 transition metal; R 1 s and R 2 s are each independently one selected from the group consisting of: a hydrogen atom, a C 1-20 alkyl radical, a C 6-20 aryl radical, a silyl radical, a C 2-20 alkenyl radical, a C 7-20 alkylaryl radical, a C 7-20 arylalkyl radical, and a metalloid radical of Group 14 substituted with a C 1-20 hydrocarbyl, wherein R 1 and R 2 can be connected to each other by an alkylidene radical containing a C 1-20 alkyl or aryl radical to form a ring; each of the R 3 s are independently one selected from the group consisting of: a hydrogen atom, a halogen radical, a C 1-20 alkyl radical, a C 6-20 aryl radical, a C 1-20 alkoxy radical, a C 6-20 aryloxy radical, and an amido radical, wherein at least two R 3 s can be connected to each other to form an aliphatic or aromatic ring; and Q 1 and Q 2 are each independently one selected from the group consisting of: a halogen radical, a C 1-20 alkylamido radical, a C 6-20 arylamido radical, a C 1-20 alkyl radical, a C 2-20 alkenyl radical, a C 6-20 aryl radical, a C 7-20 alkylaryl radical, a C 7-20 arylalkyl radical, and a C 1-20 alkylidene radical; —[Al(R 8 )—O] a — Formula 5 where, each of the R 8 s are independently one selected from the group consisting of: a halogen radical; a C 1-20 hydrocarbyl radical; and a C 1-20 hydrocarbyl radical substituted with a halogen atom; and a is an integer of 2 or greater; D(R 8 ) 3 Formula 6 where, D is aluminum or boron, and R 8 is as described above; and [L-H] + [Z(A) 4 ] − or [L] + [Z(A) 4 ] − Formula 7 where, L is a neutral or cationic Lewis acid; H is a hydrogen atom; Z is a Group 13 atom; and each of the As are independently a C 6-20 aryl or C 1-20 alkyl radical in which at least one hydrogen atom is substituted with a halogen atom, or a C 1-20 hydrocarbyl radical, C 1-20 alkoxy radical, or a phenoxy radical.
