Abstract
The present invention relates to superabsorbent polymer and a method for preparing the same. More specifically, the present invention relates to superabsorbent polymer with improved properties, comprising a dual cross-linking structure derived from alkyleneglycol multifunctional (meth)acrylate and modified nanoclay, and a method for preparing the same. According to the present invention, the modified nanoclay and alkyleneglycol multifunctional (meth)acrylate are used as internal crosslinking agents in the process of preparing superabsorbent polymer, thus contributing to improvement in the cross-linking degree and the properties of superabsorbent polymer.
