ABSORBENT ARTICLES UNDERSTANDING SUPERABSorbent POLYMERIC MATERIALS COATED WITH THERMOPLASTICS An absorbent article comprises an upper sheet, a support sheet that can be attached to the top sheet and an absorbent core positioned between the top sheet and the support sheet. In addition, the absorbent core comprises at least one superabsorbent polymeric material comprising from about 55 to about 99.9% by weight of monomer containing polymerizable unsaturated acid group, and from about 0.001 to about 5% by weight of internal cross-linking, which are polymerized and prepared as particles of superabsorbent polymer, and which also includes surface additives. The superabsorbent polymeric material can also have a degree of neutralization of more than about 25%. The result is an absorbent article that exhibits better performance, as well as greater comfort and confidence for the user. |
