Abstract
The present disclosure relates to a preparation method of a super absorbent polymer, and there is provided a preparation method of a super absorbent polymer capable of achieving anti-caking while maintaining excellent absorption-related physical properties of super absorbent polymer particles by performing surface cross-linking at a relatively lower temperature than before using a non-epoxy cross-linking agent without an epoxy-based surface cross-linking agent, which is a controversial source of chemical hazards.
