发明名称 BIODEGRADABLE SUPERABSORBENT POLYMER COMPOSITION WITH GOOD ABSORPTION AND RETENTION PROPERTIES
摘要 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, iv. incorporation of a starch compound in one or at least two of the variants V1 to V6, V1. in process step i. into the monomer solution V2. after process step i. and prior to process step ii. into the hydrogel V3. in process step ii. V4. after process step ii. and prior to process step iii. into the water-absorbing polymer structure V5. in process step iii V6. after process step iii onto the surface-crosslinked water-absorbing polymer structure. The present invention also related 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.
