Abstract
The present disclosure relates to a method for preparing a super absorbent polymer. More specifically, it relates to a method for preparing a super absorbent polymer capable of improving drying efficiency, reducing a generation amount of re-fines, and simultaneously improving absorption performance, in particular, absorption under pressure and permeability of the finally prepared super absorbent polymer by controlling granulation strength of the extruded fine reassembly.
