A PROCESS FOR PRODUCING AN IMPROVED DRYING OIL WHICH COMPRISES CONTACTING A MIXTURE OF CONJUNCT HYDROCARBON POLYMERS OF POLYOLEFINIC CYCLIC STRUCTURE WITH AN OXYGEN-CONTAINING GAS AT A SUPERATMOSPHERIC PRESSURE AND AT A TEMPERATURE OF FROM ABOUT -30* TO ABOUT 200* C. FOR A TIME SUCH AS TO REACT AN APPROXIMATELY EQUIL-MOLECULAR PROPORTION OF OXYGEN WITH SAID CONJUNCT POLYMERS, SAID POLYMERS HAVING BEEN RECOVERED BY DECOMPOSITION OF A CATALYST-HYDROCARBON SLUDGE FORMED IN A CONJUNCT POLYMERIZATION REACTION OF A HYDROCARBON MIXTURE CONTAINING MONO-OLEFINS OF AT LEAST 3 CARBON ATOMS PER MOLECULE AND SAID POLYMERS BOILING BETWEEN ABOUT 150* AND 450* C. AND HAVING BROMINE NUMBERS ABOVE ABOUT 140, MALEIC ANHYDRIDE VAULUES OF FROM ABOUT 30 TO BONDS PER MOLECULE OF FROM ABOUT 2.5 TO ABOUT 4, OF WHICH FROM ABOUT 40% TO ABOUT 70% ARE CONJUGATED.
