Abstract (en)
[origin: US2012085971A1] A process for producing thermally surface postcrosslinked water-absorbing polymer particles, wherein the water-absorbing polymer particles are coated before, during or after the thermal surface postcrosslinking with at least one polyvalent metal salt, and the polyvalent metal salt comprises the anion of glycolic acid or the anion of a glycolic acid derivative.
