Abstract:
1. An superabsorbent polymer composition comprising a superabsorbent polymer, a deswell triggering agent (TA D ) and a reswell triggering agent (TA R ); wherein the superabsorbent polymer, the TA D and the TA R are all selected from either solubility-based chemistry or neutralization-based chemistry groupings; wherein the TA D comprises a first water-soluble solid chemical wherein the TA D has a release profile for releasing the water-soluble solid chemical wherein the release profile is selected from a singular release profile or a sigmoidal release profile; wherein the TA R comprises a second water-soluble solid chemical wherein the reswell triggering agent has a sigmoidal release profile for releasing the second water-soluble solid chemical; wherein the first water-soluble chemical has a higher cumulative release than the second water-soluble chemical after exposure to aqueous fluid and before about 100% release.
