Abstract
THE PRESENT INVENTION PROVIDES A PROCESS FOR SELECTIVE HYDROGENATION OF A CONJUGATED DIENE POLYMER. THE PROCESS INCLUDES BRINGING THE CONJUGATED DIENE POLYMER IN AN INERT ORGANIC SOLVENT INTO CONTACT WITH HYDROGEN IN THE PRESENCE OF A SPECIFIC HYDROGENATION CATALYST COMBINATION INCLUDING (A) A SUBSTITUTED OR UNSUBSTITUTED BIS(CYCLOPENTADIENYL) GROUP VIII TRANSITION METAL COMPOUND AND (B) AN ORGANIC LITHIUM COMPOUND. THE HYDROGENATION CAN BE CARRIED OUT IN THE PRESENCE OF A SMALL AMOUNT OF THE HYDROGENATION CATALYST COMBINATION UNDER MILD CONDITIONS, AND BOTH THE HYDROGENATION CONVERSION AND SELECTIVITY TO CONJUGATED DIENE UNITS ARE HIGH.
