Abstract: A dual-surface treated composite superabsorbent particle comprising a polycarboxylate polymer (e.g., saponified polyacrylamide) and a carboxylated starch polymer is disclosed. The surface of the particle is cross linked through esterification with a C2-C4 polyol exemplified with glycerol. In addition, the surface region is crosslinked through ionic bonds with a trivalent metal ion exemplified with aluminum. In a critical method of making, the acidification of the surface with the polyol occurs prior to treatment with the trivalent metal ion, which results is a hybrid particle that can include up to about 40% of carboxymethyl starch yet exhibit a FSC of at least 47 g/g, a CRC of at least 27 g/g, an AUL of at least 18 g/g under a load of 0.7 psi, and a SFR of at least 180 ml/min. Also disclosed is a method of making that includes a surface esterification prior to aluminum treatment.

Abstract: Surface-treated carboxyalkylated polysaccharides comprising a biobased content of at least 82% are described herein. The surface-treated carboxyalkylated polysaccharides comprise a CRC of at least 18 g/g, a FSC of at least 26 g/g, and an AUL at 0.7 psi of at least 14 g/g. Processes for the manufacture of surface-treated carboxyalkylated polysaccharides are also described herein.
