The present invention relates to a preparation method for a super absorbent polymer capable of minimizing loss of air bubbles during foaming polymerization through radical polymerization. According to the preparation method of the present invention, a large number of small and uniform pores are formed to prepare a super absorbent polymer having a high surface area, and the super absorbent polymer exhibits an excellent absorption rate, and thus can be used in various products requiring high absorption properties. La présente invention concerne un procédé de préparation d'un polymère super-absorbant pouvant réduire au minimum la perte de bulles d'air pendant la polymérisation par moussage par polymérisation radicalaire. Selon le procédé de préparation de la présente invention, un grand nombre de pores petits et uniformes sont formés pour préparer un polymère super-absorbant ayant une surface élevée, et le polymère super-absorbant a un excellent taux d'absorption, et peut ainsi être utilisé dans divers produits nécessitant des propriétés d'absorption élevées. 본 발명은 라디칼 중합법을 통한 발포 중합 시 기포의 손실을 최소화할 수 있는 고흡수성 수지의 제조방법에 관한 것이다. 본 발명의 제조방법에 따르면 작고 균일한 기공이 다수 형성되어 높은 표면적을 갖는 고흡수성 수지를 제조할 수 있으며, 상기 고흡수성 수지는 우수한 흡수 속도를 나타내므로 높은 흡수 물성을 요구하는 다양한 제품에 활용될 수 있다.
