    摘要： An article having a refastenable tape system comprising a flexible substrate having a tear strength, and an adhesive tape member having a peel adhesion value which is greater than the tear strength of the substrate when the tape member is adhered to a first major surface of the substrate. A reinforcement layer composed of a hot melt adhesive is bonded to a second major surface of the substrate located opposite to the first major surface. The reinforcement layer exhibits an elongation-at-break of at least about 100%. The substrate and the reinforcement layer thereby provide a composite tear strength greater than the peel adhesion value of the tape member, and provide a composite elongation-at-break of at least about 100%.

    摘要： A method for making modified poly(ethylene oxide) by graft polymerizing thereto organic monomers containing a trialkoxy silane functional group or a moiety that reacts with water to form a silanol group, such as methacryloxypropyl trimethoxy silane, onto the poly(ethylene oxide) is disclosed. The graft polymerization is accomplished by mixing the poly(ethylene oxide), the silane-containing monomer(s) and an initiator and applying heat. Preferably, the method is a reactive-extrusion process. The resulting modified poly(ethylene oxide) has improved water absorption characteristics and melt processabilities and may be used to make thermally processed articles, such as fibers, films and foams, that have improved properties over articles similarly processed from unmodified poly(ethylene oxide).

    摘要： A process for making an absorbent composite including absorbent fibers, superabsorbent polymer and, optionally, thermoplastic fibers and other ingredients is provided. The synthesis (i.e., polymerization) of the superabsorbent is completely integrated into the process for forming the absorbent composite. Specifically, the polymerization of superabsorbent is initiated from within a plurality of absorbent and/or thermoplastic fibers, which are then formed into a web. The integrated process eliminates the need for separate manufacture of superabsorbent polymer prior to the fiber forming and web forming processes. Also, the superabsorbent polymer thus formed tends to disperse better and remain adhered to the absorbent and/or thermoplastic fibers, providing a stable and uniform absorbent composite for various end use applications.
