THE PROCESS OF TREATING AN UNSATURATED FATTY OIL WHICH COMPRISEES BLOWING THE UNSATURATED FATTY OIL TO ADD OXYGEN TO THE MOLECULES OF THE OIL, FORMING A MIXTURE OF THE BLOWN OIL WITH BORON FLUORIDE AS POLYMERIZATION CATALYST IN THE PROPORTION OF AT LEAST 0.01 PART FOR 100 PARTS BY WEIGHT OF THE OIL, AND MAINTINING THE MIXTURE AT A TEMPERATURE BETWEEN ROOM TEMPERATURE AND 250* F. UNTIL THE VICOSITY OF THE OIL IS EQUIVALENT TO THE VISCOSITY OF AN UNDILUTED OIL HAVING A VISCOSITY IN EXCESS OF 100 POISES, THE OIL SO PRODUCED HAVING A GREATER TOLERANCE FOR MINERAL SPIRITS THAN THE UNSATURATED OIL THICKENED BY BLOWING ALONE TO THE SAME VISCOSITY.
