Abstract
The present disclosure relates to a preparation method of a super absorbent polymer composition. More specifically, it relates to a preparation method of a super absorbent polymer composition capable of pulverizing the hydrogel polymer to a normal particle size without agglomeration between particles by adding an additive having a specific structure, reducing manufacturing cost by simultaneously performing a drying process and a surface cross-linking process, and significantly reducing the amount of fine powder generated during the process.
