Superabsorbent polymers comprising direct covalent bonds between polymer chain segments

摘要

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. <IMAGE>
