Abstract
Superabsorbent polymer (SAP) hydrogels were synthesized by copolymerization of acrylic acid and 2-acrylamido-2-methyl propane sulfonic acid and their sodium salts. The effects of reaction variables were optimized. SAPs were treated with chemical reagents. The structures and the morphologies of untreated and treated SAP hydrogels were analyzed by different techniques. The swelling/deswelling kinetics of SAP hydrogels, pH and salt sensitivity were investigated. The results show that these samples imbibed about 4310±27 g/g in deionized water, 269±18 g/g in artificial blood and 288±11 g/g in artificial urine. The highest swelling, reversible pH-responsiveness and salt sensitivity of hydrogels widen their applications.
