Compounded surface treated carboxyalkylated starch polycrylate composites |
| 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. |
