Title
(EN) METHOD FOR PREPARING SUPERABSORBENT RESIN, AND SUPERABSORBENT RESIN
(ZH) 用于制造超吸收性聚合物的方法及超吸收性聚合物
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 layerwhich 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.
