    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： Water-absorbent resins having an average particle diameter of 100 to 600 .mu.m and a particle diameter distribution of 0.35 or less are prepared by polymerizing an aqueous solution of a water-soluble ethylenically unsaturated monomer, pulverizing and sieving the gel-like polymer so obtained, and crosslinking the surface of the polymer powder. In an alternative process, an aqueous solution of the monomer having a viscosity greater than 15 cps is dispersed in a hydrophobic organic solvent and polymerized to obtain a polymer powder, and the surface of the polymer powder is crosslinked.
