Claims20
A superabsorbent polymer (SAP), comprising a polysaccharide-based polymer comprising one or more crosslinks formed between a crosslinking agent and one or more carboxyl groups and/or carboxamide groups of the polysaccharide-based polymer, wherein the SAP exhibits a Surge Index value greater than 27, a Capacity Index value greater than 2900, or both a Surge Index value greater than 27 and a Capacity Index value greater than 2900.
A superabsorbent polymer (SAP), comprising a polysaccharide-based polymer comprising one or more crosslinks formed between a crosslinking agent and two or more carboxyl groups of the polysaccharide-based polymer, one or more crosslinks formed between a crosslinking agent and two or more carboxamide groups of the polysaccharide-based polymer, or one or more crosslinks formed between a crosslinking agent and a carboxyl group and a carboxamide group of the polysaccharide-based polymer, wherein functional groups of the SAP are at least partially neutralized and the SAP exhibits a Capacity Index value greater than 2900.
A superabsorbent polymer having a Surge Index greater than 2.7 and/or a Capacity Index of at least 3000.
A superabsorbent polymer having a Surge Index greater than 3.2 and/or a Capacity Index of at least 4000.
