  A process for hydrogenation of a conjugated diene polymer. The conjugated diene polymer in an inert organic solvent is brought into contact with hydrogen in the presence of a hydrogenation catalyst composition to selectively hydrogenate the unsaturated double bonds in the conjugated diene units of the conjugated diene polymer. The hydrogenation catalyst composition includes: (I) a titanium compound; (II) a compound represented by formula (II): 1 wherein L is a Group IVB element, R is C 1 -C 12 alkyl or C 1 -C 12 cycloalkyl, X can be the same or different and is C 1 -C 12 alkyl, C 1 -C 12 alkoxy, C 1 -C 12 cycloalkoxy, halogen, or carbonyl; and (III) a trialkylaluminum compound.
