A PROCESS FOR THE POLYMERIZATION OF POLYMERIZABLE OLEFIN HYDROCARBONS WHICH COMPRISES CONTACTING POLYMERIZABLE OLEFIN HYDROCARBONS WITH A CATALYST CONSISTING OF COBALT OXIDE SUPPORTED ON ACTIVATED CARBON, SAID CATALYST PREPARED BY IMPREGNATING AN AMMONIATED ACTIVATED CARBON SUPPORT WITH A COBALT SALT DISSOLVED IN AMMONIUM HYDROXIDE, SAID COBALT SALT BEING DECOMPOSIBLE TO A COBALT OXIDE AND BEING SELECTED FROM THE GROUP CONSISTING OF COBALT CARBOXYLATE AND COBALT CARBONATE, DRYING THE RESULTING IMPREGNATED ACTIVATED CARBON SUPPORT, AND ACTIVATING SAID IMPREGNATED ACTIVATED CARBON SUPPORT BY HEATING IN AN INERT ATMOSPHERE AT TEMPERATURES OF FROM 200*C. TO 550*C.
