摘要： The present invention relates to absorbent compositions which exhibit swelling, deswelling, and reswelling behavior. More specifically, absorbent compositions of this invention swell and absorb fluids after exposure to aqueous fluids, deswell and release fluids from the swollen absorbent compositions, and may also reswell and absorb fluids. The swelling-deswelling-reswelling behavior allows enhanced liquid distribution in absorbent composites.

摘要： A process is described for recycling superabsorbent polymer fines into a process that includes treating the superabsorbent polymer fines with caustic and a polymerization step for making the superabsorbent polymer gel. The process requires treating the superabsorbent polymer fines with a caustic, followed by mixture with polymerizable monomer solution, and polymerizing the mixture of the superabsorbent polymer fines and monomer to form the aqueous fluid absorbent polymer. In the process, the fines are incorporated into the new polymer gel and become indistinguishable there from. The gel may then be comminuted into a particulate dried and then separated into a portion having a desired minimum particle size in a fines portion having less than the desired size. The particulate may then be coated with a surface crosslinking agent and surface additives and heated for surface conversion.

One sheet processing system includes a receiver adapted to receive first and second single page sheets to be processed. The first sheet originates from a stack of first sheets, and the second sheet originates from a stack of second sheets. In some systems, the first and second sheets are of different sizes. The system includes a first read head adapted to read a first identifier from the first sheet, and a second read head adapted to read a second identifier from the second sheet. A circuit coupled to the first and second read heads is adapted to compare the first and second identifiers to determine whether a match exists. At least one identifier may include a magnetic stripe.
