Abstract
(EN)
The present invention provides a superabsorbent resin exhibiting further improved absorbency under pressure and permeability, and a method for preparing the superabsorbent resin. The superabsorbent resin may comprise: a base resin powder comprising a cross-linked polymer of a monomer comprising a water-soluble ethylene-based unsaturated compound or a salt thereof; and a cross-linked surface layer which is formed on the base resin powder, and in which the cross-linked polymer is additionally cross-linked, wherein a hollow glass particle having a micron-scale particle size is included on the cross-linked surface layer.

La présente invention concerne une résine superabsorbante présentant une capacité d'absorption sous pression et une perméabilité davantage améliorées ainsi qu'un procédé de préparation de la résine superabsorbante. La résine superabsorbante peut comprendre : une poudre de résine de base comprenant un polymère réticulé d'un monomère comprenant un composé insaturé à base d'éthylène soluble dans l'eau ou un sel correspondant ; et une couche de surface réticulée qui est formée sur la poudre de résine de base et dans laquelle le polymère réticulé est en outre réticulé, une particule creuse de verre présentant une grosseur de particule à l'échelle micrométrique étant comprise sur la couche de surface réticulée.
