Patent ID: 7833926

Claim:
An arylphenoxy-based transition metal catalyst of Formula 1, which includes a cyclopentadienyl group and an arylphenoxide group as fixed ligands bound to a transition metal, wherein the ligands are not crosslinked to each other: wherein M is a group IV transition metal of the periodic table; Cp is a cyclopentadienyl group forming an ↓ 5 -bond with the transition metal, or a derivative thereof; R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , and R 8 are independently a hydrogen atom, a halogen atom, a C 1 -C 20 linear or nonlinear alkyl group optionally substituted with one or more halogen atoms, a silyl group which contains the C 1 -C 20 linear or nonlinear alkyl group optionally substituted with one or more halogen atoms, a C 6 -C 30 aryl group optionally substituted with one or more halogen atoms, a C 7 -C 30 arylalkyl group optionally substituted with one or more halogen atoms, a C 1 -C 20 alkylalkoxy group optionally substituted with one or more halogen atoms, a C 3 -C 20 alkyl-substituted siloxy group, or a C 6 -C 20 aryl-substituted siloxy group, optionally with the proviso that substituent groups may be optionally bonded to form rings; each X is independently selected from a halogen atom, a C 1 -C 20 alkyl group, a C 7 -C 30 arylalkyl group, an alkoxy group containing the C 1 -C 20 alkyl group, a C 3 -C 20 alkyl-substituted siloxy group, or an amido group having a C 1 -C 20 hydrocarbon group; Y is a hydrogen atom, a halogen atom, a C 1 -C 20 linear or nonlinear alkyl group optionally substituted with one or more halogen atoms, a silyl group containing a C 1 -C 20 linear or nonlinear alkyl group optionally substituted with one or more halogen atoms, a C 6 -C 30 aryl group optionally substituted with one or more halogen atoms, a C 7 -C 30 arylalkyl group optionally substituted with one or more halogen atoms, a C 1 -C 20 alkylalkoxy group optionally substituted with one or more halogen atoms, a C 3 -C 20 alkyl substituted siloxy group, a C 6 -C 20 aryl-substituted siloxy group, an amido group or a phosphido group which has a C 1 -C 20 hydrocarbon group, or a C 1 -C 20 alkyl-substituted mercapto or nitro group; and n is 1 or 2 depending on the oxidation state of the transition metal.
