  • Method for producing saturated polymers and saturated or unsaturated blends
    Patent number: 6486263
    Abstract: The present invention provides a method to improve the efficiency of ROMP-hydrogenation and ROMP-hydrogenolysis processes. Thus the invention provides a means for increasing the rate of reaction of the hydrogenation step of the ROMP-hydrogenation process via the addition of non-inert solvent such as methanol. The present invention permits multiple cycles of ROMP-hydrogenation-ROMP and ROMP-hydrogenolysis-ROMP without additional catalyst, thus allowing the formation of tailored polymer blends in a ‘one-pot’ reaction. Moreover, the ROMP-hydrogenation reactions of the present invention may be carried out at pressures as low as atmospheric pressure.
