ABSTRACT:
A process for making hydrogenated polymers is presenting. Polymerization is initiated with a lithium initiator and one or more unsaturated monomers are polymerized to a polymer cement. The polymerization process is terminated and dry carbon dioxide is introduced to the polymer cement to make a CO.sub.2 -treated polymer cement. The CO.sub.2 -treated polymer cement is hydrogenated in the presence of a Ni/Al catalyst.
