Abstract:
The present invention relates to a superabsorbent polymer exhibiting excellent heat stability.

Claim (Index 8):
A superabsorbent polymer comprising:\n a base resin powder comprising crosslinked polymer formed by the crosslinking polymerization of water soluble ethylenically unsaturated monomers having acid groups of which at least a part are neutralized, in the presence of an internal crosslinking agent comprising a compound represented by the following Chemical Formula 1 in the content of 80 wt % or more, based on the total weight of the internal crosslinking agent; and a surface crosslink layer on the base resin powder, formed by the additional crosslinking of the crosslinked polymer, wherein absorption property change rate at high temperature (Y) calculated by the following Calculation Formula 1 is \u22128% to 8%, and P 1  in the Calculation Formula 1 is 60 to 85 g//g: in the Chemical Formula 1, R 1  is a divalent organic group derived from C1-10 alkane, and R 2  is hydrogen or a methyl group,\n Y={[P 1 \u2212P 2 ]/P 1 }*100 \u2003\u2003[Calculation Formula 1] \n in the Calculation Formula 1, Y is absorption property change rate at high temperature, P 1  the sum of centrifuge retention capacity (CRC) of the superabsorbent polymer to a saline solution, and absorbency under load (AUL) of 0.7 psi of the superabsorbent polymer to a saline solution, measured before exposed to high temperature, and P 2  is the sum of CRC and AUL of the superabsorbent polymer, measured after leaving the superabsorbent polymer in an oven of 185\u00b0 C. for 60 minutes.
