Water-soluble surface active agents from olefin polymers

Claim 1

A PROCESS FOR PRODUCING WATER-SOLUBLE TERTIARY ALKENYL SULFONATES OF PROPYLENE POLYMERS HAVING 15 TO 18 CARBON ATOMS PER MOLECULE WHICH COMPRISES DISSOLVING PROPYLENE POLYMERS BOILING WITHIN THE RANGE OF 220* TO 320* C. IN A PARAFFINIC HYDROCARBON SOLVENT, ADMIXING CHLORSULFONIC ACID AND A DIALKYL ETHER HAVING ABOUT 4 CARBON ATOMS PER MOLECULE WITH THE RESULTING PARAFFINIC HYDROCARBON SOLUTION OF THE POLYMERS, MAINTAINING THE RESULTING MIXTURE AT A TEMPERATURE IN THE RANGE OF ABOUT -10* TO +50* C., REMOVING HYDROGEN CHLORIDE GAS EVOLVED FROM THE SOLUTION, NEUTRALIZING THE RESULTING MIXTURE PRODUCT IN THE SOLUTION WITH AQUEOUS SODIUM HYDROXIDE, SEPARATING WATER-SOLUBLE TERTIARY ALKENYL SULFONATES BY EXTRACTION WITH AN AQUEOUS ALCOHOL FROM THE HYDROCARBON SOLUTION, WASHING THE AQUEOUS ALCOHOL EXTRACT OF TERTIARY ALKENYL SULFONATES FREE OF HYDROCARBON NAPHTHA-SOLUBLE MATERIALS WITH A NAPHTHA HYDROCARBON SOLVENT, THEN DRYING THE WASHED AQUEOUS ALCOHOL EXTRACT TO RECOVER THE WATER-SOLUBLE TERTIARY ALKENYL SULFONATES AS A SOLID.
