Latest Patents
Tokoro's latest patents include innovative processes for producing hydrogenated products of cyclic olefin polymers. The first patent describes a method that involves polymerizing a cyclic olefin through ring-opening polymerization in the presence of a catalyst containing organoruthenium or organoosmium compounds. This process is followed by a hydrogenation step that adds a hydrogenation catalyst and hydrogen to the polymerization system, effectively hydrogenating the carbon-carbon double bonds of the resulting polymer. The inclusion of a carbene compound in the catalyst enhances its activity for the ring-opening polymerization.
The second patent similarly outlines a process for producing hydrogenated ring-opening polymerization polymers of cycloolefins. This method also utilizes organoruthenium or organoosmium compounds as catalysts and follows the same polymerization and hydrogenation steps, emphasizing the efficiency of the process when a carbene compound is present.
