Abstract

A method for preparing a superabsorbent polymer, and more particularly, a method for preparing a superabsorbent polymer in which it is possible to stably operate a process for preparing a fine powder reassembly while maintaining assembly strength of the fine powder reassembly, wherein a refined ratio is reducible, and an initial absorption speed of the superabsorbent polymer is improved, by adjusting a stirring speed and divisionally adding water to a fine powder in a process for the preparation of the fine powder reassembly, is provided.
