This invention relates to a process for selectively hydrogenating the unsaturated double bonds of conjugated diene units of a homopolymer or copolymer. By using a highly active novel homogeneous organo titanium catalyst represented by formula (I) and lithium hydride (LiH) prepared in
The present invention relates to a process for polymer hydrogenation that includes: polymerizing or copolymerizing at least one conjugated diene in a hydrocarbon solvent using an organic alkali metal polymerization initiator to generate a living polymer; adding a terminating agent se
The present invention provides an effective process for removal of the residual metal catalyst from a polymer solution using water and alcohol containing an inorganic acid after selective hydrogenation of the unsaturated olefinic double bonds in a polymer of a conjugated diene monome
This invention is to provide a process for the hydrogenation of conjugated diene polymer in an inert organic solvent, said polymer being obtained by polymerization or copolymerization of a conjugated diene, which comprise effecting selective hydrogenation of unsaturated double bonds in t
