Cellulose graft copolymer containing non-ionic and ionic polymer moieties as absorbent media in absorbent dressings

摘要

A backbone of natural or regenerated cellulose in fibrous form which has side chains of polymer moieties grafted thereto (cellulose graft copolymer) provides a novel, highly water-absorbent, soft, non-flammable, fibrous material useful for a variety of water or aqueous fluid-absorbent products particularly body fluid absorbent dressings such as diapers, sanitary napkins, tampons, surgical sponges, and the like. The polymer side chains are made up of ionic and non-ionic polymer moieties and, on a weight basis, may amount to from about 10% to about 90% of the cellulose graft copolymer. The ionic polymer moieties comprise from about 10% to about 80% by weight of the cellulose graft copolymer, and the non-ionic polymer moieties comprise from about 0.5% to about 60% by weight of the cellulose graft copolymer.
