  • Patent number: 10016954
    Abstract: Geocomposite articles that can provide a barrier against high conductivity water e.g., ocean water, are described and their method of manufacture, for waterproofing surfaces that contact high conductivity water. The geocomposite article mat includes a woven or non-woven geotextile sheet or mat containing a powdered or granular partially cross-linked acrylamide/acrylate/acrylic acid copolymer across its entire major surface(s). The powdered or granular copolymer has an unexpectedly high free-swell when hydrated with High Conductivity water, such as ocean water. A liquid-impermeable cover sheet is adhered to the upper major surfaces of the filled copolymer-carrying geotextile to provide a primary high conductivity water barrier layer that, if ruptured, is sealed by the swell of an underlying layer of water-insoluble, partially cross-linked acrylamide/acrylic acid copolymer.

  • Publication number: 20100264044
    Abstract: A single dose dispensing package (100) having a backing (102) for maintaining the package in a substantially flat orientation is disclosed. A score (106) through the backing allows the package to open upon flexure. At least one additional score on the opposite side provides at least one metered opening in the package. Absorbent material (112) placed over the score, and adhered to the dispensing package only in the area of the score, provides controlled dispensing and application of the contents using essentially an entire surface of the absorbent material as an applicator.

  • Patent number: 6803107
    Abstract: Surface-treated superabsorbent polymer particles obtained by mixing 100 parts by weight of superabsorbent polymer particles with 0.001 to 10 parts by weight of a hydroxyalkylamide, and heating the surface-treated superabsorbent polymer particles to crosslink molecular chains existing at least in the vicinity of the surfaces of the superabsorbent polymer particles is disclosed. Surface crosslinking the superabsorbent polymer particles with a hydroxyalkylamide substantially increases both the rate of liquid absorption and the quantity of liquid absorbed and retained by the superabsorbent particles.

  • Patent number: 6623576
    Abstract: A continuous sheet having a combination of acidic and basic water-absorbing resin particles that are essentially not neutralized and can be continuously manufactured on conventional papermaking apparatus, using a wet, dry, or wet-dry process to manufacture a water-absorbent sheet-like substrate containing 50%-100% by weight of the combination of acidic and basic water-absorbent particles. The acidic and basic essentially unneutralized resins can be contained in the sheet material articles of the present invention as separate acidic and basic resin particles, or as multicomponent particles containing both the acidic and basic resins. The sheet materials can be manufactured having new and unexpected structural integrity, with little or no shakeout or loss of superabsorbent particles during or after manufacture while exhibiting exceptional water absorption and retention properties.
