Abstract
Ionic hydrogels are polymer networks that have the ability to store large amounts of water. Due to this behavior hydrogels based on sodium acrylate (SA) are mostly used in diapers and soil conditioners. In this work diffusion and exchange processes in polyelectrolyte hydrogels were followed by 23Na and 27Al magnetic resonance imaging (MRI) techniques. We present 23Na and 27Al MRI experiments of the replacement reaction in hydrogels (classical...
