Abstract: The present invention relates to superabsorbent polymer particles having functionalizers covalently bound to the surface of precursor superabsorbent polymer particles. The functionalizers of the present invention comprise a grafting unit with a radiation activatable group and a functional unit covalently bound to the grafting unit. The grafting unit is bound to an aliphatic C-H group comprised at the surface of the precursor superabsorbent polymer particle. The functional unit comprises chemical structures which are not present in the precursor superabsorbent polymer particle. These functional units add an additional function to the precursor suberabsorbent polymer particle or modifying an existing function of the precursor superabsorbent polymer particle. Moreover, the invention relates to a process for making these superabsorbent polymer particles. The present invention relates to superabsorbent polymer particles having functionalizers covalently bound to the surface of precursor superabsorbent polymer particles.

Abstract: Grafted, crosslinked cellulosic materials used in absorbent articles, the grafted crosslinked cellulosic materials including cellulose fibers and polymer chains composed of at least one monoethylenically unsaturated acid group-containing monomer (such as acrylic acid) grafted thereto, in which one or more of the cellulose fibers and the polymer chains are crosslinked (such as by intra-fiber chain-to-chain crosslinks). Some of such materials are characterized by a wet bulk of about 10.0-17.0 cm3/g, an IPRP value of about 1000 to 7700 cm2/MPa·sec, and/or a MAP of about 7.0 to 38 cm H2O. Methods for producing such materials may include grafting polymer chains from a cellulosic substrate, followed by treating the grafted material with a crosslinking agent adapted to effect crosslinking of one or more of the cellulosic substrate or the polymer chains. Grafted, crosslinked cellulosic materials used in absorbent articles, the grafted crosslinked cellulosic materials including cellulose fibers and polymer chains composed of at least one monoethylenically unsaturated acid group-containing monomer (such as acrylic acid) grafted ...more ...less
