SURFACE CROSS-LINKED SUPERABSORBER TREATED WITH A SILICA COMPOUND AND A AL3+ SALT |
摘要 |
<p>The present invention relates to a process for production of water-absorbing polymer structures comprising the process steps of providing an untreated, water-absorbing polymer structure (Pu) with a retention of at least about 35 g/g; and bringing this water-absorbing untreated polymer structure (Pu) into contact with a permeability-increasing agent. The invention further relates to the water-absorbing polymer structures obtainable by this process, water-absorbing polymer structures, a composite, a process for production of a composite, a composite obtainable by this process, chemical products comprising water-absorbing polymer structures or a composite as well as the use of water-absorbing polymer structures or of the composite in chemical products.</p> |
