    摘要： The present invention provides a particulate water absorbing agent for absorbent cores which is excellent in powder conveying property, and achieves sufficient absorption performances for use in absorbent cores in particulate water absorbing agents including a water absorbing resin as a principal component, and which further is suitable for practical applications. In the present invention, characteristics that had not been known conventionally at all, i.e., "permeability potential under pressure (PPUP)" and "frictional charge being a positive charge" of the particulate water absorbing agent are regulated at a time, and furthermore, regulation of the "moisture content of 2 to 10% by weight" is perfected. Also, the particulate water absorbing agent including (A) a water-swelling crosslinked polymer having a constitutional unit derived from an unsaturated monomer containing an acid group and/or a salt thereof; and (B) water fulfills certain requirements.

    摘要： Hydrophilic polymer is modified with a gaseous modifier or a powdered modifier made from a liquid modifier. To powder a liquid modifier, the liquid modifier is mixed with a water-insoluble compound, or the liquid modifier is cooled below its melting point to solidify it. With these methods it is possible to modify a hydrophilic polymer uniformly. When a gaseous modifier is used, the hydrophilic polymer and the modifier can be made to react efficiently and safely regardless of the size and shape of the hydrophilic polymer. When a hydrophilic polymer is modified with a powdered modifier, it is possible to uniformly mix a liquid modifier, virtually in a solid state, with a hydrophilic polymer and to easily control the timing of the modification.
