Abstract

The present invention relates to superabsorbent polymer particles with improved surface cross-linking and their use in absorbent articles. The superabsorbent polymer particles of the present invention comprise polymer chain segments, wherein at least a part of the polymer chain segments are covalently cross-linked to each other and wherein at least a part of the cross-links comprise the reaction product of cross-linking molecules having at least two C=C double bonds and further comprise the reaction product of radical former molecules. These cross-links are present at surfaces of the superabsorbent polymer particles. Moreover, theinvention relates a method for making these superabsorbent polymer particles.
