Patent ID: 7588822

Claim:
An absorbent article comprising surface cross-linked superabsorbent polymer particles, said superabsorbent polymer particles being made by a method which comprises the steps of: a) providing superabsorbent polymer particles having a surface and a core and having a degree of neutralization of more than 60 mol-%; b) applying one or more Brønsted acids onto the surface of the superabsorbent polymer particles; and either c1) exposing said superabsorbent polymer particles to irradiation with vacuum UV radiation having a wavelength from about 100 nm to about 200 nm or c2) exposing said superabsorbent polymer particles to irradiation with UV radiation having a wavelength from about 201 nm to about 400 nm and wherein further to the Brønsted acids, radical former molecules are applied to the surface of the superabsorbent polymer particles.
