Abstract

A water-absorbent resin composition excelling in an absorption capacity under pressure, a first transition of initial absorption, and the small amount of rewet is provided. It comprises a water-absorbent resin obtained by aqueous solution polymerization and by reversed-phase suspension or reversed-phase emulsion polymerization and shows a CSF of not less than 20 g / g or an AAP of not less than 20 g / g or an SFC of not less than 10 (unit: 10 -7 × cm 3 × s X g -1 ). The gaps among resin particles owing to the difference in shape form optimum gap widths for the sake of capillarity. The resin composition consequently formed, therefore, manifests such excellent properties without the influences of a surfactant or an emulsifier.

Description

technical field

[0001] The present invention relates to a water-absorbent resin composition which is a mixture of water-absorbent resins obtained in various forms and by different polymerization methods, which has excellent absorption characteristics such as absorption capacity, permeability (permeation of physiological saline flow capacity), capillary absorption capacity, the first transition of initial absorption, and reduce the rewet of the absorbed liquid. Background technique

[0002] Water-absorbent resins capable of absorbing water tens to hundreds of times their own weight have been developed, and have been used for absorption and water retention. For example, firstly, in hygienic materials including hygienic products and disposable diapers, fields of agricultural and gardening materials, Food fields that require freshness preservation, anti-condensation and heat insulation professional fields. As such water-absorbent resins, hydrolyzed products of starch-acrylonitr...
