Latest Patents
One of Sakabe's latest patents is a process for manufacturing cycloolefin addition polymer. This innovative process involves polymerizing monomers containing a cycloolefin compound using a catalyst that includes a nickel or palladium compound. The addition polymerization occurs in the presence of a molecular weight controlling agent and is executed in two steps. The first step initiates the polymerization reaction using no more than 80 wt % of the total monomers, while the second step supplies the remaining monomers during the reaction. This method results in a cycloolefin addition polymer with uniform quality, narrow molecular weight distribution, and excellent mechanical strength, all achieved at a high polymerization conversion rate. The process is designed to operate at highly controlled temperatures, making it suitable for industrial manufacturing.
