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 a non-reactive or latent crosslinking agent, and contains a plurality of micropores having a size of about 150 μm or less. The superabsorbent material is formed into a variety of shapes having a high external surface to volume ratio.
