Document Type and Number:
WIPO Patent Application WO/2015/199222
Kind Code:
A1
Abstract:
[Problem] To provide a method for manufacturing an industrially useful hydrogenated polymer, whereby a high rate of hydrogenation can be achieved using an amount of catalyst that is sufficiently small that there is no need for a decalcification step. [Solution] A method for manufacturing a hydrogenated polymer, characterized by comprising hydrogenating, with molecular hydrogen, a carbon-carbon double bond based on a conjugated diene structural unit of a polymer in which at least a portion of a living polymer obtained by polymerizing monomers containing at least one type of conjugated diene using an organic alkali metal compound as a polymerization initiator is terminated by molecular hydrogen, in the presence of a silane compound having at least one silyl hydride bond and an organic metal compound represented by general formula (I). (In the formula, R1-R10 are as defined in the specification.)
