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.
摘要翻译：亲水性聚合物用气态变性剂或由液体变性剂物质制成的粉状变性剂物质变性。液体变性剂物质通过例如将液体变性剂物质与水不溶性化合物混合的方法制成粉末，将液体变性剂物质冷却至其熔点以下以使其变为固态的方法。因此，亲水性聚合物可以均匀地变性。亲水性聚合物在气态变性剂变性的情况下，无论亲水性聚合物的尺寸或形状如何，亲水性聚合物和变性剂以安全的方式有效地彼此反应。亲水性聚合物与粉末状变性剂变性的情况下，不仅可以将基本上处于固体状态的液体变性剂与亲水性聚合物混合，而且可以容易地控制变性定时。

摘要： The invention provides a water-absorbing agent, which has high absorption capacity and excellent absorption efficiency under increased pressure and can display excellent water absorption properties when used for sanitary materials even if the resin concentration of a water-absorbent resin is high. The water-absorbing agent has an absorption capacity of 30 (g/g) or more and the below-defined absorption efficiency of 0.7 or more under increased pressure. This agent can be obtained by heating in the presence of a surface-crosslinking agent a water-absorbent resin having an absorption capacity of 40 (g/g) or more and an amount of an eluting component of 1 wt % or less relative to the water-absorbent resin, or by: polymerizing a water-absorbent resin in the presence of a chain transfer agent; treating the polymerized resin with a hydrophilic solution; and heating the treated resin in the presence of a surface-crosslinking agent. ##EQU1##
