| titleOfInvention | Method for hydrogenating conjugated diene polymers |
| abstract | (57) [Problem] When a conjugated diene polymer obtained by polymerizing an organic alkali metal compound as a polymerization initiator is contacted with hydrogen in an inert organic solvent to hydrogenate a double bond of a conjugated diene, The present invention provides an industrially advantageous method in which a hydrogenation catalyst is stable and easy to handle, does not require an alkali metal compound as a cocatalyst, uses a very small amount of a catalyst, and can be quantitatively hydrogenated with good reproducibility in a wide temperature range. . SOLUTION: When a deactivator is added to a conjugated diene polymer obtained by polymerizing an organic alkali metal compound as a polymerization initiator, and the conjugated diene polymer is brought into contact with hydrogen in an inert hydrocarbon solvent to hydrogenate a conjugated diene double bond. And (MZ + Al-Ti) / Ti in the range of -6 to +2 in the presence of the catalyst of the following component (A). The component (A) is an organometallic compound represented by the following general formula: (However, R 1 to R 10 represent hydrogen, a C 1 to C 12 hydrocarbon group or a C 1 to C 12 alkylsilyl group and may be the same or different. X represents a halogen atom or a methyl group. .) M is the molar amount of the organic alkali metal compound; Z is the molar amount of the deactivator, Al is the molar amount of the organic aluminum compound, and Ti is the molar amount of the organic titanium compound. |
