Beschreibung
Zusammenfassung:	An absorbent composite that can handle complex fluids and maintain high absorbent capacity under high loads even after the material has been subjected to rigorous processing conditions. The absorbent composite includes an inhomogeneously crosslinked superabsorbent polymer having a highly crosslinked outer shell. The surface of the superabsorbent polymer includes a protective fibrous coating material and an association agent. La présente invention concerne un composite absorbant qui peut traiter des fluides complexes tout en conservant une capacité d'absorption élevée sous des charges élevées même après que le matériau ait été soumis à des conditions de traitement rigoureuses. Ce composite absorbant inclut un polymère superabsorbant réticulé de façon non homogène garni d'une enveloppe extérieure hautement réticulée. La surface du polymère superabsorbant inclut un matériau de revêtement fibreux protecteur et un agent d'association.
