Abstract
Disclosed are a granular super absorbent polymer, including particles (A) having an average diameter of 150 to 850 μm, wherein the particles (A) includes particles (a1) having an average diameter of 500 to 850 μm; and particles (a2) having an average diameter of 150 to 250 μm, and the particles (a1 and a2) have a water-solubility index of 0.08 to 2.0 (represented by Equation 1), thereby it is possible to maintain a proper amount of extractables in a resin, and to exhibit excellent flow conductivity and water absorption ability in a case of being actually applied to products, without inducing any skin problem when, as well as a preparation method thereof.
