Abstract
A preparation method of a superabsorbent polymer, and a superabsorbent polymer prepared thereby are provided. The preparation method of the superabsorbent polymer according to the present disclosure prevents polymer particles from being broken or the surface thereof from being damaged during preparation and handling of the superabsorbent polymer, thereby providing a superabsorbent polymer having excellent absorption properties and permeability.
