    • The invention relates to fine-grained water-absorbent polymer particles with a high fluid transport and absorption capacity. According to the invention, the centrifugal retention capacity (CRC) is at least 26 g/g, the absorption under a load of 4.83 kPa (AUL0.7psi) is at least 23 g/g and the transport value (TW) is at least 15,000 cm 3 s, whereby the transport value (TW) is the product of a fluid transfer (SFC) and wick absorption after 60 minutes (DA 60 ) multiplied by 10 7 and the wick absorption after 60 minutes (DA 60 ) is the quantity of a solution containing 0.9 wt. % common salt that is absorbed by 70 g of the water-absorbent polymer particles in 60 minutes. The water-absorbent polymer particles are held in a circular container with an internal diameter of 6 cm during the measuring process, the bottom of said container being sealed by a screen base with a mesh size of 36 µm and the screen base being in pressureless contact with a solution containing 0.9 wt. % common salt. The invention also relates to a method for producing said particles and to their use in sanitary articles and packaging materials.
