Process for selective hydrogenation of conjugated diolefin polymers |
| abstract |
This is an improved process for the hydrogenation of conjugated diolefin polymers which comprises polymerizing or copolymerizing at least one conjugated diolefin with an organo alkali metal polymerization initiator in a suitable solvent thereby creating a living polymer, terminating the polymerization by the addition of hydrogen and effecting selective hydrogenation of the unsaturated double bonds in the conjugated diolefin units of the terminated polymer by contacting the polymer, in the absence of hydrocarbon lithium and alkoxy lithium compounds, with hydrogen in the presence of at least one bis(cyclopentadienyl)titanium compound. The improvement is the use of methyl benzoate as a promoter in the hydrogenation step. |
