Abstract: Water-absorbent polymer particles with a centrifugal retention capacity (CRC) of at least 26 g/g and a transport value (TW) of at least 15000 cm 3>.s, where TW is the product of saline flow conductivity and wick absorption after 60 minutes multiplied by 10 7>. Water-absorbent polymer particles (I) containing (a) unsaturated monomer unit(s) with acid groups, (b) crosslinker unit(s), (c) optionally one or more ethylenic and/or allylic unsaturated comonomer unit(s), (d) optionally one or more water-soluble polymers onto which monomers (a)-(c) are at least partly grafted, and (e) converted post-crosslinker(s). These particles (I) show a centrifugal retention capacity (CRC) of at least 26 g/g and a transport value (TW) of at least 15000 cm 3>.s, where TW = the product of fluid transfer (saline flow conductivity; SFC) and wick absorption after 60 minutes (DA60) multiplied by 10 7>, and DA60 = the amount of 0.9 wt% sodium chloride solution absorbed by 70 g (I) in 60 minutes in a circular vessel with an internal diameter of 6 cm, closed at the bottom with a sieve plate of mesh size 36 microns which is in unpressurised contact with 0.9 wt% NaCl solution. Independent claims are also included for (1) a method for the production of (I) by making a graft copolymer from components (a)-(d), drying and classifying the copolymer, treating with crosslinker (e), drying and thermally crosslinking (2) hygiene articles containing (I) .
