Abstract

See full text

The present invention relates to a superabsorbent polymer showing a low degree of decrease in absorption capacity, and a preparation method thereof. Specifically, the present invention provides a superabsorbent polymer having an excellent rewetting prevention ability such that moisture hardly leaks out under pressure even after a certain time, and a preparation method thereof, by preparing an acrylic resin with a high molecular weight main chain that is evenly cross-linked for maintaining high gel strength by minimizing an amount of an initiator with respect to a monomer.
