摘要：
Provided are a preparation method of a superabsorbent polymer, and a superabsorbent polymer prepared thereby. The preparation method of the superabsorbent polymer according to the present disclosure enables preparation of the superabsorbent polymer which is excellent in absorption properties such as centrifuge retention capacity and absorbency under pressure, and also has improved permeability. In addition, the preparation method exhibits excellent operability during the preparation (in particular, surface crosslinking of the polymer) and excellent productivity due to low production of coarse particles and fine particles.
