ABSTRACT:
Starch-based superabsorbents are extended by blending with highly modified, low molecular weight starches. The dextrinized starches synergistically interact with the superabsorbents thereby permitting dilution without a commensurate reduction in the water absorbency. While the principal utility of the blends is the absorption of aqueous fluids, when hydrated they yield soft, smooth gels useful as high-quality thickening agents.
