INTRODUCTION
Water swellable polymeric networks have received considerable attention from both academic and applied laboratories (1). The capacity of highly ionized gels to retain large amounts of water makes the gels useful as reservoirs as well as in the retention of inorganic/organic substances and thus for new applications in separation technology. The sources of the varying water bonding capacities and the underlying molecular structures that govern the stability of the hydrogels have been largely unexplained (2).
A gel always consists of a three-dimensional polymeric network and a fluid. If the interactions of the components are strong enough, ...
