    Abstract: 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.

    Abstract: The invention relates to a method for producing a water-absorbing resin by polymerization of a reaction mixture comprising at least one hydrophilic monomer and optionally at least one cross-linker, in a reactor. According to said method, at least one first fraction of a particulate additive is admixed to the reaction mixture before the reaction mixture reaches a dwell time of 40 % of the total dwell time in the reactor, and at least one second fraction of a particulate additive is admixed when the reaction mixture reaches a dwell time of 45 % or more of the total dwell time in the reactor. The additive is selected from the group of water-adsorbing resin powders, fillers and mixtures thereof, the total solids content of the monomer and the additive being 30 to 60 % by weight, the amount of the additive being 5 to 50 % by weight, based on the monomer, and the weight ratio of the first fraction to the second fraction of the additive being 10:1 to 1:5. The resin powder is constituted of, e.g., recycled fines. Bot the residual monomer content, especially the residual cross-linker content, and the content in extractable substances of the water-absorbing resin are reduced by the described manner of admixture. A high percentage of additives can be incorporated without deteriorating the properties of the water-absorbing resin so obtained. The additives form a sufficiently strong compound with the resin without excessive dust formation when the resin is exposed to mechanical stress.
