Abstract: The present invention relates to a superabsorbent polymer composition. The superabsorbent polymer composition of the present invention may exhibit very improved antimicrobial and deodorizing properties without deterioration of the properties of superabsorbent polymer such as centrifugal retention capacity, absorbency under pressure, and transmittance, and thus, can be usefully applied for hygienic goods such as a diaper, and the like. The superabsorbent polymer composition comprises: superabsorbent polymer particles comprising crosslinked polymer of water-soluble ethylenically unsaturated monomers including acid groups, of which at least a part are neutralized; and a particulate antimicrobial agent comprising a quaternary ammonium salt of a silane-based compound.

Abstract: Provided are methods of evaluating deodorizing ability of a superabsorbent polymer and a product including the same. According to the methods of evaluating deodorizing ability of the present invention, deodorizing ability of the superabsorbent polymer and the product including the same may be evaluated by measuring changes in the concentration of ammonia naturally generated in a wet state which is made close to the actual use environment. Accordingly, the deodorizing ability of the superabsorbent polymer and the product including the same may be evaluated more accurately and efficiently.
