Beschreibung
Zusammenfassung:	Provided is a method of preparing a superabsorbent polymer. More particularly, provided is a method of preparing a superabsorbent polymer, in which degradation of physical properties of the polymer due to a mechanical force generated during a surface crosslinking process is minimized by controlling operating conditions of a surface crosslinking reactor in the step of surface crosslinking, thereby improving absorption properties of the superabsorbent polymer finally prepared.
