    • Provision of, in a process of producing a hydrogenated polymer, which comprises steps of sequentially performing, in the presence of a ruthenium carbene complex, a ring-opening metathesis polymerization reaction of a cyclic olefin and a hydrogenation reaction of a ring-opening metathesis polymer produced by the polymerization reaction to give a hydrogenated polymer, a simple and economic process of obtaining a hydrogenated polymer having an extremely small content of residual ruthenium derived from the ruthenium carbene complex.A process of producing a hydrogenated polymer, which comprises, in the presence of a ruthenium carbene complex, subjecting a cyclic monoolefin and/or a cyclic diolefin to a ring-opening metathesis polymerization, hydrogenating the resulting ring-opening metathesis polymer to give a hydrogenated polymer, and bringing the hydrogenated polymer in contact with a poor solvent of the hydrogenated polymer in the presence of dissolved hydrogen to allow precipitation. As the poor solvent of the hydrogenated polymer, alcohol having 1 to 6 carbon atoms, ketone having 3 to 6 carbon atoms and the like are preferable.

    • The process of the invention is provided to achieve uniform doping of an activator metal into phosphor particles and to improve efficiency of utlization of a metal element to be used in the production of a Group II metal sulfide phosphor and a precursor thereof. Specifically, the object of the invention is achieved by a process for producing a Group II metal sulfide phosphor precursor, comprising adding to an organic solvent an aqueous solution containing at least one of a Group II element compound, a sulfurizing agent, and a compound containing any of copper, silver, manganese, gold, and rare-earth elements to obtain a reaction mixture, heating the reaction mixture to produce an azeotrope of the water and the organic solvent, and removing the water from the reaction mixture to produce a desired Group II metal sulfide in the reaction mixture, wherein the removal of the water from the reaction mixture is carried out by recovering only the water condensed from a vapor produced by the azeotropic distillation.
