<p>A hydrogenation method in which a conjugated diene polymer is hydrogenated in the presence of both a catalyst comprising a platinum-group metal or compound thereof and a basic compound. Specifically, (1) hydrogenation is conducted in a reaction system obtained by adding the catalyst and a basic compound to a solution or latex of the conjugated diene polymer; (2) hydrogenation is conducted in a reaction system obtained by adding a hydrogenation catalyst system comprising a combination of the catalyst and a basic compound to a solution or latex of the conjugated diene polymer; or (3) hydrogenation is conducted in a reaction system obtained by adding the catalyst to a solution of a conjugated diene polymer composition containing a basic compound. Thus, a conjugated diene polymer can be efficiently and industrially advantageously produced using a small amount of a catalyst.</p> |
