Hydrocarbon drying oil production

Claim 1

A CONTINUOUS PROCESS FOR PRODUCING A HYDROCARBON DRYING OIL WHICH COMPRISES MIXING 75 TO 85 PARTS OF BUTADIENE, 25 TO 15 PARTS OF STYRENE, 200 TO 300 PARTS OF STRAIGHT-RUN MINERAL SPRITS BOILING BETWEEN ABOUT 150 AND 200* C., 10 TO 35 PARTS OF P-DIOXANE, 1 TO 3 PARTS OF FINELY DISPERSED SODIUM METAL AND 10 TO 20% OF ISOPROPYL ALCOHOL BASED ON THE WEIGHT OF SODIUM, HEATING THE MIXTURE TO A REACTION TEMPERATURE BETWEEN 65 AND 95* C. AND CONTINUOUSLY PASSING THE HEATED MIXTURE THROUGH A NARROW TUBULAR ZONE TO ACTIVATE THE MIXTURE, THE LENGTH OF THE TUBULAR ZONE BEING SUCH THAT PASSAGE OF THE MIXTURE THERETHROUGH TAKES ABOUT 5 TO 30 MINUTES, THEREAFTER AGITATING THE MIXTURE IN A CLOSED POLYMERIZATION TANK AT REACTION TEMPERATURE UNTIL THE MONOMER CONVERSION OF AT LEAST 65% IS REACHED, AND CONTINUOSLY WITHDRAWING THE PARTIALLY POLYMERIZED MIXTURE IN LINEAR FLOW THROUGH A SECOND TUBULAR ZONE MAINTAINED AT REACTION TEMPERATURE, THE LENGTH OF SAID SECOND TUBULAR ZONE BEING SUCH THAT COMPLETE CONVERSION OF SAID TUBULAR ZONE BEING SUCH THAT SAGE THERETHROUGH.
