Patent ID: 8431660

Claim:
A transition metal compound which is represented by the following Formula 1: wherein R 1 to R 3 are each independently a hydrogen atom; alkyl having 1 to 20 carbon atoms; aryl that is unsubstituted or substituted by a fluoroalkyl, nitro, sulfonate or halogen group and having 6 to 20 carbon atoms; alkenyl having 2 to 20 carbon atoms; alkylaryl having 7 to 20 carbon atoms; arylalkyl having 7 to 20 carbon atoms; a halogen group; a nitro group; a sulfonate group; a siloxyl group (—OSiZ 3 , where Z is an aryl group having 6 to 12 carbon atoms or an alkyl group having 1 to 12 carbon atoms); or a hydrocarbylene group (—(RO)zR′, where R is an alkylene group having 2 to 12 carbon atoms or an arylene group having 6 to 12 carbon atoms, R′ is an alkyl group having 1 to 12 carbon atoms and an aryl group having 6 to 20 carbon atoms, and z is in the range of 1 to 4), and R 1 and R 2 may be connected to each other to form a ring, A is selected from the group consisting of a hydrogen atom, a branched-chained alkyl group having 3 to 6 carbon atoms, NO 2 , a halogen group, a persulfonate (SO 3 − ) group, sulfonyl ester (SO 2 R), a carboxyl group (COO—), a perfluoroalkyl group, an alkoxy group, and carboxylate and sulfonate that includes cations of alkali metal or alkali earth metal, Xs may be the same as or different from each other, and is halogen group, an alkyl group having 1 to 20 carbon atoms, an allyl group, a benzyl group, a nitro group, an amido group (—N(R) 2 ), an alkylsilyl group having 1 to 20 carbon atoms, an alkoxy group having 1 to 20 carbon atoms, or a sulfonate group, and M is a Group 4 transition metal selected from the group consisting of titanium, zirconium and hafnium.
