 water-absorbent polymer particles obtainable by the process according to the invention. The present invention further provides surface-postcrosslinked water-absorbent polymer particles having a centrifuge retention capacity from 00 to 00 g/g, an absorption under high load from 00 to 00 g/g, a level of extractable constituents of less than 00% by weight, and a porosity from 00 to 00%.
