| titleOfInvention | Post treatment of surface-crosslinked water-absorbent polymer particles employing an additive |
| abstract | The invention generally relates to a process for the preparation of post-treated surface-crosslinked water-absorbent polymer particles, comprising the process steps of (i) preparing an aqueous monomer solution comprising at least one partially neutralized, monoethylenically unsaturated monomer bearing carboxylic acid groups (α1) and at least one crosslinker (α3); (ii) optionally adding fine particles of a water-absorbent polymer; (iii) adding a polymerization initiator or at least one component of a polymerization initiator system to the aqueous monomer solution; (iv) optionally decreasing the oxygen content of the aqueous monomer solution; (v) charging the aqueous monomer solution into a polymerization reactor; (vi) polymerizing the monomers in the aqueous monomer solution, thereby obtaining a polymer gel with a water content in the range from 40 to 60 wt.-%; (vii) discharging the polymer gel out of the polymerization reactor and optionally comminuting the polymer gel; (viii) drying the optionally comminuted polymer gel, wherein the obtained dried polymer gel has a water content in the range from 0.5 to 25 wt.-%; (ix) grinding, thereby obtaining water-absorbent polymer particles; (x) sizing the ground water-absorbent polymer particles; (xi) contacting with a further crosslinker, thereby obtaining surface-crosslinked water-absorbent polymer particles; (xii) sizing the surface-crosslinked water-absorbent polymer particles; (xiii) contacting the sized surface-crosslinked water-absorbent polymer particles with Ag-zeolite particles in an amount in the range from 100 to 5000 wt.-ppm, based on the total weight of the sized surface cross-linked water-absorbent polymer particles, thereby obtaining post-treated surface-crosslinked water-absorbent polymer particles. |
