| titleOfInvention | An improved method for selective hydrogenation of conjugated diene polymers. |
| abstract | (57) [Summary] [Constitution] At least one conjugated diene is polymerized or copolymerized with an organic alkali metal polymerization initiator in a suitable solvent to produce a living polymer, and hydrogen is added to terminate the polymerization. , Then in the non-presence of a lithium hydrocarbon and an alkoxylithium compound, in the presence of at least one bis (cyclopentadienyl) titanium compound, in the conjugated diene unit of the terminated polymer by contacting the polymer with hydrogen. Providing an improved method of hydrogenation of conjugated diene polymers, which comprises selectively hydrogenating the double bonds of [Effect] The improvement is to use an alkyl benzoate as a promoter in the hydrogenation step, which enhances the catalytic activity, so that the amount of the catalyst used may be small. Methyl benzoate is the most preferred accelerator. |
