PURPOSE: Unsaturated double bond of conjugated diene polymer is hydrogenated to high yield by a new catalyst. CONSTITUTION: The unsaturated double bond of conjugated diene polymer and copolymer of the conjugated diene monomer and aromatic vinyl monomer are selectively hydrogenated. The diene polymer and copolymer are prepared by living polymerization using organic alkali metal initiator, and a terminal of the living polymer is inactivated by hydrogenation. Double bond of the obtained polymer is hydrogenated at 0-150°C, 1- 100 kg-f/cm¬2 for 15-1440 minutes by monocyclopentadienyl titanium compound(formula 1; R1 and R2 are same or not, F, Cl, Br and I; R3, R4, R5 and R6 are same or not, C1-C12 alkyl or alkoxy group, C6- C20 aryl, aryloxy or cycloalkyl group; R7 is C2-C4 alkyl, ether group, O or S) and hydrogen.
