摘要：
The present invention relates to a super absorbent polymer and a method for preparing the same. According to the super absorbent polymer and the method for preparing a super absorbent polymer of the present invention, a laponite is contained in a colloidal solution state during polymerization of the monomer composition, and thus achieves an appropriate crosslinking density, thereby contributing to improvement of various physical properties such as a gel strength and a centrifuge retention capacity of the super absorbent polymer.
