Abstract:
The present invention relates to a superabsorbent polymer having excellent short time free absorbency. The superabsorbent polymer may exhibit excellent centrifuge retention capacity and absorbency under load, as well as excellent short time free absorbency. Thus, it can fundamentally solve the problems of the existing superabsorbent polymer and technical requirement of the art, and can provide various hygienic goods exhibiting more excellent properties.

Claim (Index 1):
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, and inorganic material; and a surface crosslink layer on the base resin powder, formed by the additional crosslinking of the crosslinked polymer, wherein short time free absorbency calculated by the following Calculation Formula 1 is 500 g/g or more: 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 SFA=( Y 1 \u2212Y 3 )/ Y 2 *100\u2003\u2003[Calculation Formula 1] \n in the Calculation Formula 1, SFA is the short time free absorbency of superabsorbent polymer, and Y 3  is the weight of a filtrate obtained by adding Y 2  g of superabsorbent polymer to Y 1  g of distilled water, stirring at 500 rpm for 10 minutes, and then, filtering with a 20 mesh screen.
