The present invention relates to superabsorbent polymer particles with improved 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 processes for making these superabsorbent polymer particles.
L'invention concerne des particules polymères superabsorbantes à réticulation améliorée et leur utilisation dans des articles absorbants. Les polymères superabsorbants selon l'invention sont constitués de segments de chaînes polymères qui sont au moins partiellement réticulés les uns aux autres par le biais de liaisons covalentes directes. De plus, l'invention concerne des procédés de fabrication de ces particules polymères superabsorbantes.
