    摘要： A method for preparing a super absorbent polymer and a superabsorbent polymer prepared from the same are disclosed herein. In some embodiments, a method includes mixing super absorbent polymer particles, water and an additive form a hydrated super absorbent polymer, wherein the super absorbent polymer particles comprise a base polymer powder including a cross-linked polymer polymerized from a water-soluble ethylenically unsaturated monomer having an acidic group of which at least a part is neutralized, and a surface cross-linked layer formed on the base polymer powder, wherein the surface cross-linked layer is formed by further cross-linking the cross-linked polymer, and wherein the additive including a polyoxyalkylene aliphatic hydrocarbon ether carboxylic acid. The method can appropriately control the water content of the super absorbent polymer by water-addition or the like to suppress crushing or the like during transfer, and also can suppress deterioration of physical properties.

    摘要： The present disclosure relates to a preparation method of a super absorbent polymer containing a novel cross-linking agent compound. The preparation method of a super absorbent polymer of the present disclosure can provide a super absorbent polymer exhibiting excellent absorption properties and an excellent deodorizing effect by including a cross-linking agent with a novel structure. Therefore, according to the present disclosure, since a separate additive for a deodorizing property is not required, processability and economic efficiency of the manufacturing process can be improved.

    摘要： A method of preparing a super absorbent polymer and a superabsorbent polymer prepared from the same are disclosed herein. In some embodiments, a method includes mixing a mixture comprising fines having a particle diameter of 150 μm or less, a surface-modified inorganic material having a reactive functional group, and water, and drying the mixture to prepare a fine powder reassembly. There may be provided a super absorbent polymer exhibiting excellent absorption properties and mechanical properties such as crushing strength while having uniform particle size distribution by effectively reassembling fines obtained inevitably in the preparation of a super absorbent polymer.
