The invention relates to water-absorbing polymer particles made of crosslinked polymer chains which largely comprise mono-polymerized units of at least partly neutralized acrylic acid. The polymer particles have a) a proportion of particles with a particle size of 150 to 300 [mu]m of at least 20 wt.%, b) a total swell rate of all the polymer particles FSR of at least 0.25 g/g-s, c) a difference delta FSR of at least 0.15, d) a centrifuge retention capacity CRC of at least 25.0 g/g, and e) a permeability of the swollen gel bed SFC of at least 90*10-7 cm3-s/g. delta FSR is defined as delta FSR = FSR 150-300 [mu]m - FSR in total, wherein FSR represents 150-300 [mu]m for the swell rate of the polymer particles with a particle size of 150 to 300 [mu]m. the absorption capacity of all the polymer particles is also largely used when segregating particles of different sizes.
