Hydrogenated modified polymer, process for producing the same and composition containing the same

摘要

A hydrogenated modified polymer obtained by hydrogenating a modified polymer having at least one primary amino group and/or at least one secondary amino group in a conjugated diene-based polymer obtained by anion-polymerizing a conjugated diene or a conjugated diene and another monomer. <??>A hydrogenated modified polymer obtained by polymerizing a conjugated diene or a conjugated diene and another monomer using an organic alkali metal compound as a polymerization initiator, adding an alkoxysilane compound to the resulting conjugated diene-based polymer to terminate the reaction to obtain a modified polymer, which is hydrogenated.
