METHOD FOR PRODUCING SATURATED POLYMERS AND SATURATED OR UNSATURATED BLENDS

摘要

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 permit s 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.
