The present invention relates an absorbent material consisting of a molecular network of starch molecules, the starch molecules comprising an amylopectin content of at least 90% (w/w). The molecular network can either be comprised of self-entangled starches or cross-linked starches.

Starch networks as absorbent or superabsorbent materials and their preparation by extrusion

The present invention relates to discrete particulate composite additives for superabsorbent polymers and includes a method of making same. The discrete particulate composite additives generally comprise a polysaccharide and an inert inorganic component. Advantageously, these discrete particulate composite additives functionally improve superabsorbent performance. They are suitable for a number of applications, including the use and manufacture of hygiene products.

Polysaccharide-inorganic composite particles as performance additives for super-absorbent polymers

The present invention relates to an absorbent or a superabsorbent nanocomposite material comprising a polysaccharide and a phyllosilicate. The polysaccharide component can be a biodegradable polysaccharide that is a self-entangled glass-like polysaccharide or a crosslinked polysaccharide. The phyllosilicate component can be an exfoliation or a semi-exfoliation clay.
