ABSTRACT:
Disclosed is a composition comprising a hydrophobic polymer phase and a water-swollen superabsorbent polymer phase. Also disclosed is a two component system for preparing a composition comprising a hydrophobic polymer phase and a water-swollen superabsorbent polymer phase. The first component is an emulsion of the hydrophobic polymer; the second component comprises the superabsorbent polymer; and the first and second components form the composition when mixed.
