摘要：
Summary Method of Preparing a Super Absorbent Polymer and a Super Absorbent Polymer Prepared by the present invention relates to a method of preparing a superabsorbent polymer (sap) and a sap prepared therefrom. The method of the present invention includes the steps of preparing a first hydrogel polymer by performing a thermal polymerization or photopolymerization of a monomer composition including a water-soluble unsaturated ethylene-based monomer and a polymerization initiator； preparing a second hydrogel polymer by performing a thermal polymerization or photopolymerization of a monomer composition including a water-soluble unsaturated ethylene-based monomer and a polymerization initiator； drying and milling the first hydrogel polymer and distributing the first hydrogel polymer to a fine powder with a particle diameter below 150 µm and a base resin having a particle diameter of 150 µm to 850 µm； manufacturing a reassembled body of the fine powder by mixing the fine powder and the second hydrogel polymer； and mixing the reassembled body of the fine powder with the first hydrogel polymer, and drying and milling it, wherein the second hydrogel polymer has a greater water holding capacity than the first hydrogel polymer. According to the present invention, sap having high water retention capacity and fine dust aggregation resistance, without diminishing the absorption power under pressure and penetrability can be obtained.resumo método de preparação de um polímero super absorvente e um polímero super absorvente preparado pelo mesmo a presente invenção refere-se a um método de preparação de um polímero super-absorvente (sap) e um sap preparados a partir desse. o método da presente invenção inclui os passos de preparação de um primeiro polímero de hidrogel através da realização de uma polimerização térmica ou foto polimerização de uma composição de monômeros incluindo um monômero à base de etileno insaturado solúvel em água e um iniciador de polimerização； a preparação
