PREPARATION METHOD OF SUPER ABSORBENT POLYMER

摘要

PURPOSE: A method for preparing a high absorbent polymer is provided to obtain a high absorbent resin with low moisture content and low temperature by discharging moisture or heat within the high absorbent polymer. CONSTITUTION: A method for preparing a high absorbent polymer comprises the steps of: forming a monomer composition including a water-soluble ethylene-based unsaturated monomer and non-reactive microparticles with 20 nm ~ 1 mm of diameter; and performing thermal polymerization or UV polymerization of the monomer composition. The non-reactive microparticles comprise nanoclay particles, resin particles or inorganic particles.
