ABSTRACT:
There is provided a method for selectively hydrogenating living polymers having olefinic double bonds, in which the living polymers resulting from the polymerization initiated by alkyllithium compound are deactivated by contacting the polymerization terminators for a short time under a mild condition and hydrogenated in the presence of bis(cyclopentadienyl)titanium compound in high efficiency and high reproducibility without adjusting accurate molar ratio of the lithium compound to the titanium compound.
