摘要 |
A process for hydrogenating a conjugated diene polymer wherein a conjugated diene polymer is hydrogenated in the presence of a catalyst comprising a platinum group metal or its compound, and a basic compound. More specifically, (1) hydrogenation is conducted in a reaction system prepared by incorporating the catalyst and the basic compound in a solution or latex of the conjugated diene polymer; (2) hydrogenation is conducted in a reaction system prepared by incorporating a catalyst system comprising a combination of the catalyst with the basic compound, in a solution or latex of the conjugated diene polymer; or (3) hydrogenation is conducted in a reaction system prepared by incorporating the catalyst in a solution of a composition comprising the conjugated diene polymer and the basic compound. Thus, a hydrogenated conjugated diene polymer can be efficiently and industrially advantageously produced using a small amount of a catalyst. |
