The expansion is caused by the osmosis of sodium ions found in the polyacrylate structure. These ions break off and form a osmosis gradient, but subsequently makes reuse of polymer difficult as many of the sodium ions are no longer present in the structure after one evaporates all the water. Each expansion/evaporation cycle should greatly reduce the rate of absorption.
