Abstract
A method of preparing a super absorbent polymer and a superabsorbent polymer prepared from the same are disclosed herein. In some embodiments, a method includes mixing a mixture comprising fines having a particle diameter of 150 μm or less, a surface-modified inorganic material having a reactive functional group, and water, and drying the mixture to prepare a fine powder reassembly. There may be provided a super absorbent polymer exhibiting excellent absorption properties and mechanical properties such as crushing strength while having uniform particle size distribution by effectively reassembling fines obtained inevitably in the preparation of a super absorbent polymer.
