摘要： The present invention relates to absorbent articles comprising surface cross-linked superabsorbent polymer (SAP) particles, the SAP particles being made by a method using UV irradiation. The method is carried out in a so-called drum reactor, which comprises a hollow drum and an irradiation source. The drum has a longitudinal axis and a cross-section. Superabsorbent polymer particles are fed into the drum and are irradiated while they move within the drum, which is rotated around its longitudinal axis. The irradiation source is provided such that the radiation emitted by the irradiation source is able to reach superabsorbent polymer particles within said drum. The irradiation source for use in the method of the present invention is able to emit UV radiation of a wavelength between 100 nm and 200 nm.

The superabsorbent polymer particles for use in the method of the present invention have a relatively high degree of neutralization. Brønsted acids are selectively applied onto the surface of the superabsorbent polymer particles to selectively facilitate a relatively high number of protonated carboxyl groups at the surface of the superabsorbent polymer particles while the relatively high degree of neutralization in the core of the superabsorbent polymer particles remains substantially unaffected.
