The present invention relates to a preparation method of a super-absorbent polymer. More specifically, the present invention relates to a preparation method of a super absorbent polymer, the method controlling the initial pore formation speed of the polymer during the drying stage, thereby reducing the amount of crumbs generated and thus producing a super absorbent polymer that has excellent drying efficiency and excellent absorption properties. La présente invention concerne un procédé de préparation d'un polymère superabsorbant. Plus spécifiquement, la présente invention concerne un procédé de préparation d'un polymère superabsorbant, le procédé commandant la vitesse de formation de pores initiale du polymère pendant l'étape de séchage, ce qui permet de réduire la quantité de grumeaux générés et de produire ainsi un polymère superabsorbant qui présente une excellente efficacité de séchage et d'excellentes propriétés d'absorption. 본 발명은 고흡수성 수지의 제조 방법에 관한 것이다. 보다 구체적으로, 건조 공정 중 중합체의 초기 공극 형성 속도를 제어함으로서, 발생되는 미건조체의 함량을 감소시켜 우수한 건조 효율과 우수한 흡수 물성을 가지는 고흡수성 수지의 제조 방법에 관한 것이다.
