Abstract
A superabsorbent polymer which has excellent initial absorbency and keeps water from flowing out under pressure even after the passage of a long period of time, in which the superabsorbent polymer keeps water from flowing out under pressure even after the passage of a long period of time to exhibit excellent absorbency, and also has an anti-caking property under conditions of high temperature and high humidity to improve storage stability, is provided. The superabsorbent polymer composition of the present invention may be used to improve physical properties of a variety of diapers, potty training pants, incontinence pads, etc., thereby being applied to production of personal absorbent hygiene products having high absorbency and excellent storage stability under conditions of high temperature and high humidity.
