Abstract:
1. An absorbent-entrained polymeric structure defining an outer layer and an interior region, said structure comprising a thermoplastic material and at least one absorbent, wherein said absorbent is entirely entrained within said thermoplastic material, wherein said structure has a greater concentration of absorbent in the outer layer of the polymeric structure than in the interior region, and wherein said thermoplastic material is selected from the group consisting of a copolymer containing at least two of the same monomers, a mixture of at least two polymers from single monomers, each polymer of which contains the same monomer, a mixture of at least two copolymers, each copolymer having a common monomer, a mixture of at least one polymer from a single monomer and at least one copolymer, wherein the polymer and the copolymer have a common monomer, and combinations thereof.
