  • Absorbent article
    Publication number: 20030135172
    Abstract: A storage layer obtainable by a process including (a) forming a sprayable blend containing one or more superabsorbent forming monomers; superabsorbent polymer particles; water; and one or more initiators; (b) applying the sprayable blend to a fibrous web; and (c) subjecting the sprayed fibrous web to conditions under which the superabsorbent forming monomer polymerizes. The storage layer is used in absorbent articles to store aqueous fluids.

  • Absorbent article
    Publication number: 20030045847
    Abstract: Absorbent articles and processes for making absorbent articles are provided. The process includes spraying onto a fibrous web a blend containing superabsorbent polymer particles, superabsorbent forming monomer, initiator and water, and subjecting the web to polymerization conditions. The resulting web is useful as an absorbent article particularly in disposable hygiene products.
