    摘要: A method for removing an organic solute from a solution, comprising contacting the solution with a polymer formed by copolymerizing one or more hydrophobic monomers and one or more hydrophilic monomers, whereby the solute is adsorbed onto the polymer. The solution can comprise a polar solvent such as a polar organic solvent or water or an aqueous buffer. The hydrophobic monomer can be, for example, divinylbenzene. The hydrophilic monomer can be, for example, a heterocyclic monomer, such as a vinylpyridine or N-vinylpyrrolidone.

    摘要: An interlabial sanitary pad is disclosed including a pickup module containing an absorbent which is adapted to fit in or adjacent to a vaginal opening, a capacity module containing an absorbent which is adapted to be positioned remote from the vaginal opening, and fluid-wicking fibers serving as the absorbent and further communicating with both the pickup and capacity modules for carrying fluid from the pickup module to the capacity module. The fluid-wicking fibers are longitudinally oriented and packed in the capacity module at a bulk density greater than in the pickup module. The pickup module has a fluid-pervious cover, while the capacity module has a fluid-impervious baffle capable of containing fluid therein. The capacity module can have a flattened fan shape and can contain superabsorbent.

    摘要: A generally hydrophobic polyester article is provided with a generally hydrophilic surface by contacting said general hydrophobic polyester with a copolymeric material while said polyester is at a temperature above its melting point. The copolymeric composition comprises a generally hydrophobic moiety and a generally hydrophilic moiety. Also disclosed is a method for imparting the hydrophilic surface to a generally hydrophobic polyester which method comprises contacting a generally hydrophobic polyester with a copolymeric material while said generally hydrophobic polyester is at a temperature above its melting point. In one preferred embodiment the generally hydrophobic polyester is contacted with said copolymeric composition immediately after said polyester has been extruded and while said polyester is undergoing die swell.
