摘要: This invention relates to a method for preparing super absorbent polymer and super absorbent polymer. More specifically, this invention relates to a method for preparing super absorbent polymer that can inhibit generation of fine particles during the preparation process, and simultaneously, realize excellent vortex time, by controlling the process conditions of a drying step to prepare base resin powder having relatively high moisture content, and super absorbent polymer.
