Preparation of resin-drying oil mixture

Claim 1

A PROCESS COMPRISING THE STEPS OF MIXING TOGETHER A MAJOR PROPORTION OF BUTADIENE AND A SIGNIFICANT MINOR PROPORTION OF DIISOBUTYLENE, COOLING THE MIXTURE TO A TEMPERATURE WITHIN THE RANGE BETWEEN +10* C. AND -40* C. BY THE ADDITION OF LIQUID PROPANE, POLYMERIZING THE COLD MIXTURE BY ADDING THERETO A CATALYST SOLUTION CONSISTING OF ALUMINUM CHLORIDE DISSOLVED IN ETHYL CHLORIDE, LIMITING THE POLYMERIZATION TO 60% TO 80% CONVERSION OF THE OLEFINIC MATERIAL PRESENT BY THE ADDITION OF A SMALL AMOUNT OF A CATALYST INACTIVATOR WHICH DESTROYS CATALYTIC ACTIVITY UNDER ACID CONDITIONS, THEREBY PRODUCING A LIGHT YELLOW POLYMER, RETAINING SAID POLYMER IN SOLUTION, AND IMMEDIATELY THEREAFTER TRANSFERRING THE TOTAL COLD POLYMERIZATION MIXTURE INTO A WARM DRYING FATTY OIL TO TRANSFER THE POLYMER DIRECTLY FROM THE COLD SOLUTION TO THE WARM FATTY OIL WITHOUT AT ANY TIME CONVERTING IT TO A SOLID AND WITHOUT, DISCOLORATION, THEREBY VOLATILIZING AWAY SUBSTANTIALLY ALL OF THE REMAINING PROPANE, BUTADIENE AND ETHYL CHLORIDE FROM THE FATTY OILPOLYMER MIXTURE, AND THEREAFTER HEAT BODYING THE MIXTURE OF POLYMER AND THE FATTY OIL.
