摘要（英）：

The invention provides a special catalyst composition of a hydrogenation conjugated diene polymer and a method for selectively hydrogenating the conjugated diene polymer by using the special catalyst composition. The method comprises the step of reacting conjugated diene polymer dissolved in an inert organic solvent with hydrogen in the presence of a hydrogenation catalyst composition to selectively hydrogenate unsaturated double bonds of conjugated diene units in the conjugated diene polymer. The hydrogenation catalyst composition comprises (a) a titanium compound, (b) a compound shown in a formula (II) and (c) an alkyl aluminum compound, wherein in the formula (II), R5 is alkyl, vinyl, amino, ether, ketone group or ester group of C1 to C12; R3 and R6 are alkyl or vinyl of C1 to C12; R4 and R7 are alkyl, vinyl, amino, ether, ketone group or ester group of C1 to C12; and n is more than or equal to 1 and less than or equal to 3, and m is more than or equal to 1 and less than or equal to 3.
