  • Patent number: 8563466
    Abstract: 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.
