Abstract:
A hydrogel composite comprising an interpenetrating network of a crosslinked polymer and particles of a disintegrant, wherein:said crosslinked polymer is formed from at least one ethylenically-unsaturated monomer and a multi-olefinic crosslinking agent; andsaid disintegrant is at least one of (i) a crosslinked natural or synthetic polyelectrolyte, (ii) a crosslinked neutral hydrophilic polymer, (iii) a non-crosslinked natural or synthetic polyelectrolyte having a particulate shape, (iv) a non-crosslinked neutral hydrophilic polymer having a particulate shape, or (v) a porous inorganic material that provides wicking by capillary forces.
