Abstract
The present invention relates to absorbent compositions which exhibit swelling, deswelling, and reswelling behavior. More specifically, absorbent compositions of this invention swell and absorb fluids after exposure to aqueous fluids, deswell and release fluids from the swollen absorbent compositions, and may also reswell and absorb fluids. The swelling-deswelling-reswelling behavior allows enhanced liquid distribution in absorbent composites.
