Abstract:
The present disclosure relates to a preparation method of a super absorbent polymer. More specifically, it relates to a preparation method of a super absorbent polymer capable of significantly reducing the amount of fine powder generated during the process by mixing a hydrogel polymer with an additive having a specific structure, pulverizing it, and then drying it with a paddle-type dryer.
