Biodegradable superabsorbent polymer composition with good absorption and retention properties
Abstract:
The present invention generally relates to a method for the production of a superabsorbent composition comprising the process steps: i. production of a hydrogel by radical polymerization of an aqueous monomer solution containing at least one monomer ii. drying the hydrogel to obtain a water-absorbing polymer structure iii. surface crosslinking of the water-absorbing polymer structure to obtain a surface-crosslinked water-absorbing polymer structure, and iv. incorporating a starch compound into the method. The present invention also relates to a superabsorbent composition obtainable according to this method, a particulate superabsorbent composition and a composite, a sanitary article core and a sanitary item, furthermore chemical products and also the use of this superabsorbent composition in chemical products.
