Process for producing hydrogenated hydrocarbon polymers
Abstract
Abstract HYDROGENATED HYDROCARBON POLYMERS CAN BE OBTAINED IN A CONTINUOUS STEP COMPRISING POLYMJERIZING OR COPOLYMERIZING CONJUGATED 1,3-DIOLEFIN IN AN ENERT ATMOSPHERE AND IN AN INERT SOLVENT BY USING A CATALYST BASED ON AN ALKALI METAL OR AN ALKALI METAL HYDROCARBYL TO OBTAIN A POLYMER SOLUTION AND THEN MIXING HOMOGENEOUSLY AN ORGANIC COMPOUND OF NICKEL OR COBALT SOLUBLE IN THE INERT SOLVENT WITH THE RESULTING POLYMER SOLUTION WITHOUT ISOLATING THE RESULTING POLYMER AND CATLYTICALLY HYDROGENATING THE UNSATURATED BOND OF THE RESULTING POLYMER. IN THIS PROCESS THE ALKALI METAL OR ALKALI METAL HYDROCARBYL IN THE POLYERIZATION CATALYST, WHICH REMAINS IN THE RESULTING POLYMER AFTER THE POLYMERIZATION ACTS TO EFFECT THE REDUCTION OF THE ORGANIC COMPOUND OF NICKEL OR COBALT TO PRODUCE THE HYDROGENATION CATALYST.
