A process for producing a hydrogenated product of a polymer prepared through ring-opening polymerization which comprises a polymerization step of polymerizing a cyclic olefin through ring-opening polymerization in the presence of a polymerization catalyst comprising an organoruthenium compound or an organoosmium compound to prepare a polymer, and a hydrogenation step of adding a hydrogenation catalyst and hydrogen into a polymerization system resulting from the polymerization step to hydrogenate the carbon-carbon double bonds of the polymer prepared through the ring-opening polymerization. When the organoruthenium compound- or organoosmium compound-containing catalyst further comprises a carbene compound, the catalyst exhibits a higher activity for the ring-opening polymerization.
A process for producing a hydrogenated product of a polymer prepared through ring-opening polymerization, which comprises:
A process for producing a polymer through ring-opening polymerization, characterized in that a cyclic olefin is polymerized through ring-opening polymerization using a polymerization catalyst comprising an organoruthenium compound or an organoosmium compound, and a heteroatom-containing carbene compound in the absence of a solvent or in the presence of a halogen-free solvent.
