Abstract: 

A new outlook on a preparative process of superabsorbing hydrogels is presented in this article. The hydrogels based on acrylic acid (AA), acrylamide (AM) and potassium acrylate (KA) were prepared through polymerization of concentrated solution of the acrylic monomers. Ammonium persulphate/sodium metabisulphite redox pair initiating system was used for the free radical terpolymerization and methylenebisacrylamide was used as a cross-linker. Some certain process variables (cross-linker and initiator concentration) affecting either swelling capacity or swelling rate were thoroughly investigated. Temperature variations of the polymerization mixture were also studied. The synthetic method was found to be an efficient and facile approach for making superabsorbents with quantitative yield under atmospheric conditions. Meanwhile, by swelling measurements in both water and saline media, power law relationships between cross-linker content and swelling capacity were found.
