Abstract: Provided is a method of preparing a superabsorbent polymer. More particularly, provided is a method of preparing a superabsorbent polymer, in which variations in centrifugal retention capacity of superabsorbent polymer particles to be prepared are reduced by controlling heat treatment temperature conditions in a surface crosslinking step, thereby improving absorption properties of the superabsorbent polymer finally prepared.

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 while maintaining basic absorption performance, and can significantly reduce the generation of dust during the application for a process, and thus fulfills both stability and processability and can be usefully applied for hygienic goods such as a diaper and the like. The superabsorbent polymer composition includes: a) superabsorbent polymer particles including a crosslinked polymer of water-soluble ethylenically unsaturated monomers including acid groups, of which at least a part are neutralized, and b) an antimicrobial agent having a controlled particle size, containing a chelating agent including EDTA or an alkali metal salt thereof; a mixture of an organic acid and a silicate-based salt; and an agent for controlling a particle size.
