Water soluble sodium acrylate polymers of high molecular weight
Abstract
Abstract HIGH-MOLECULAR WEIGHT WATER-SOLUBLE POLYMERS OF SODIUM ACRYLATE AND AQUEOUS GELS COMPRISING FROM 25% TO 40% BY WEIGHT THEREOF, ARE PREPARED BY IRRADIATING SOLUTIONS OF SODIUM ACRYLATE WITH HIGH ENERGY IONIZING RADIATION, AT A PH OF FROM 4 TO 14, AND AT A DOSE RATE OF LESS THAN 200,000 RADS PER HOUR TO A TOTAL DOSE OF FROM 1,000 RADS TO THAT SUFFICIENT TO CONVERT SUBSTANTIALLY ALL OF THE MONOMER TO POLYMER. POLYMERS AND AQUEOUS GELS THEREOF, HAVING INTRINSIC VISCOSITIES RANGING UPWARDS FROM 6 DECILITERS PER GRAM, MEASURED IN 2 N SODIUM HYDROXIDE AT 25*C., ARE OBTAINED OVER THE ENTIRE INDICATED RANGE OF RADIATION INTENSITIES AND TOTAL DOSAGES IN THE MORE CONCENTRATED SOLUTIONS. THE POLYMERS, OR THEIR AQUEOUS GELS, HAVE UTILITY AS THICKENING AND FLOCCULATING AGENTS.
