ABSTRACT:
A process for producing a hydrogenated conjugated diene polymer, which comprises hydrogenating the carbon-carbon double bonds of a conjugated diene polymer in a solvent using a supported catalyst composed of a hydrogenating catalyst supported on a carbon carrier having an average particle diameter of 5 m.mu. to 10.mu. and a specific surface area of 5 to 2000 m.sup.2 /g, and after the hydrogenation reaction has been completed, separating and recovering the hydrogenated conjugated diene polymer from the solution of the hydrogenated polymer without separating the catalyst therefrom.
