Zusammenfassung:	The present invention relates to a preparation method of a superabsorbent polymer. More specifically, the present invention relates to a preparation method of a superabsorbent polymer, which adjusts operating conditions of a surface cross-linking reactor in a surface cross-linking step so as to minimize the degradation of the physical properties of the resin due to mechanical forces generated during a surface cross-linking process, and thus, improve the absorption properties of the finally manufactured superabsorbent polymer. 본 발명은 고흡수성 수지의 제조 방법에 관한 것이다. 보다 구체적으로, 표면 가교 단계에서, 표면 가교 반응기의 구동 조건을 조절함으로써, 표면 가교 공정 중 발생하는 기기적 힘에 의한 수지의 물성 저하를 최소화 하였으며, 이에 따라, 최종 제조되는 고흡수성 수지의 흡수 물성을 향상시킨 고흡수성 수지의 제조 방법에 관한 것이다.
