SUPERABSORBENT POLYMERS HAVING RADIATION ACTIVATABLE SURFACE CROSS-LINKERS AND METHOD OF MAKING THEM |
摘要 |
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 a water-absorbing resin and the reaction product of a radiation activatable surface cross-linker wherein the reaction product of the radiation activatable surface cross-linker is present at surfaces of the superabsorbent polymer particles. The radiation acitvatable surface cross- linker comprises at least two radiation activatable groups R, which are covalently bound to each other or to at least one spacer group S. Moreover, the invention relates to a process for making these superabsorbent polymer particles.
