ABSTRACT:
The present invention relates to superabsorbent polymer particles with improved surface cross-linking and their use in absorbent articles.Superabsorbent polymers of the invention comprise polymer chain segments, wherein at least a part of these polymer chain segments are cross-linked to each other through direct covalent bonds.Moreover, the invention relates to a process for making these superabsorbent polymer particles.
