主权项 1. A method of preparing a superabsorbent polymer having improved anti-caking properties, comprising: a) adding a superabsorbent polymer (A) with 0.0001˜15.0 parts by weight of particles (B) having i) a BET specific surface area of 300˜1500 m2/g and ii) a porosity of 50% or more, based on 100 parts by weight of the superabsorbent polymer (A); and b) adding the superabsorbent polymer (A) and the particles (B) obtained in a) with 0.1˜20.0 parts by weight of water (C), based on 100 parts by weight of the superabsorbent polymer (A) and the particles (B), and performing at least one of heating treatment and aging time control treatment, yielding the superabsorbent polymer having improved anti-caking properties.
