Abstract
A catalyst composition and a method for hydrogenating a polymer having a conjugated diene are provided. The catalyst composition includes (a) a first composition having one of a bis(cyclopendienyl, fluorenyl, indenyl and derivatives thereof) titanium compound and a mixture thereof; (b) a second composition having one selected from the group consisting of a first compound of a formula (II), a second compound of a formula (III) and a mixture thereof:wherein the formula (II) has a chain structure, the formula (III) has a cyclic structure, the R is C1˜C12 alkyl, the X1 and X2 are ones selected from the group consisting of C1˜C12 alkyl, C1˜C12 cycloalkoxy, aryl, C1˜C12 alkyl aryl and carbonyl, and n>1 and m>2; and (c) a third composition having an organic metallic compound.
