Beschreibung
Zusammenfassung:	A superabsorbent material generally free of organic solvents and having a high overall porosity and a high percentage of micropores are provided. The superabsorbent material is formed from a high-molecular weight linear water-soluble absorbent polymer, and contains a plurality of micropores having a size of about 150 µm or less. L'invention concerne un matériau superabsorbant généralement exempt de solvants organiques et ayant une porosité globale élevée et un pourcentage élevé de micropores. Le matériau superabsorbant est formé à partir d'un polymère absorbant hydrosoluble linéaire de poids moléculaire élevé, et contient une pluralité de micropores ayant une taille d'environ au plus 150 µm.
