A process for the production of hydrogenated polymers through the step of conducting ring-opening metathesis polymerization of a cycloolefin in the p resence of a ruthenium carbene complex and hydrogenation of the obtained rin g-opening metathesis polymer successively to obtain a hydrogenated polymer, by which a hydrogenated polymer extremely reduced in the content of residual ruthenium resulting from the ruthenium carbene complex can be obtained easi ly and economically. A process for the production of hydrogenated polymers, characterized by conducting ring-opening metathesis polymerization of a cycl ic monoolefin and/or a cyclic diolefin in the presence of a ruthenium carben e complex, hydrogenating the obtained ring-opening metathesis polymer, and b ringing the obtained hydrogenated polymer into contact with a poor solvent f or the hydrogenated polymer in the presence of dissolved hydrogen to precipi tate the polymer. The poor solvent is preferably an alcohol having 1 to 6 ca rbon atoms, a ketone having 3 to 6 carbon atoms, or the like.
