摘要： A hydrophilic polymer is denatured with a gaseous denaturant or a powdery denaturant substance made from a liquid denaturant substance. The liquid denaturant substance is made into powders by, for example, a method of mixing the liquid denaturant substance with a water-insoluble compound, a method of cooling the liquid denaturant substance to or below its melting point to turn the same into a solid state. Consequently, the hydrophilic polymer can be denatured uniformly. In case that the hydrophilic polymer is denatured with a gaseous denaturant, the hydrophilic polymer and denaturant react with each other efficiently in a safe manner regardless of the size or shape of the hydrophilic polymer. In case that the hydrophilic polymer is denatured with the powdery denaturant substance, not only the liquid denaturant substance which is substantially in the solid state can be mixed with the hydrophilic polymer, but also the denaturation timing can be readily controlled.

摘要： A method of preparation of an absorbent composite in which an aqueous solution containing a water-soluble radical polymerization initiator and a water-soluble ethylenically unsaturated monomer which can be converted into an absorbent polymer by polymerization is applied to a substrate, and the monomer is polymerized while the substrate to which the aqueous solution is applied is, on both the sides, held in contact with polymerization-inert surfaces facing each other. A continuous manufacturing method includes the sequential steps of continuously passing a substrate through (1) a region applying to the substrate an aqueous solution containing a water-soluble radical polymerization initiator and a water-soluble ethylenically unsaturated monomer which can be converted into an absorbent polymer by polymerization, and (2) a region of polymerizing the monomer while maintaining the substrate, on both the sides, in contact with polymerization-inert surfaces facing each other.

摘要： This invention concerns an absorbent composite a supporting member and a cationic absorbent polymer and anionic absorbent polymer particles fixed to the supporting member. This absorbent composite excels in absorbing capacity under pressure, vertical aspiration power, and flexibility and suffers only sparing exfoliation of an absorbent polymer. This invention further concerns an absorbent composite which contains an absorbent polymer in an amount of at least 30% by weight based on the total weight of the absorbent composite and, after absorbing a liquid, shows a value of not less than 3 for the expansion anisotropy specified by the following formula. Expansion anisotropy=(Ez/Ex+Ez/Ey)/2 (wherein Ex, Ey, and Ez respectively represent coefficient of liner expansion in the directions of X axis, Y axis, and Z axis) and an absorbent article using the absorbent composite. This invention permits production of a novel absorbent composite which suffers no leakage and excels in water absorbing power, water retaining power, and flexibility and an absorbent article using the absorbent composite.
