Abstract
The present invention relates to a superabsorbent polymer which has excellent initial absorbency and keeps water from flowing out under pressure even after passage of time. The superabsorbent polymer of the present invention is characterized by simultaneously optimizing centrifuge retention capacity (CRC), absorbency under pressure (AUP), liquid permeability (SFC), and gel strength within a predetermined range. The present invention can provide improved physical properties of a final diaper product and apply an ultra-thin technology to the diaper product.
