    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: Preparation of water absorbing polymer (I) comprises polymerizing a mixture of at least one ethylenic unsaturated, acid group carrying monomer, a crosslinker and optionally a copolymerizable e.g. ethylenic unsaturated monomer and a water soluble polymer (of the monomers) to give a ground polymer (A) and treating (A) with post crosslinking agent, where before/during the polymerization, at least one water insoluble metal sulfate is added. Preparation of water absorbing polymer (I) comprises polymerizing a mixture of at least one ethylenic unsaturated, acid group carrying monomer that is partially neutralized, at least one crosslinker, optionally one or more copolymerizable ethylenic and/or allylic unsaturated monomer and optionally one or more water soluble polymer (of the monomers), which is partially grafted to give a ground polymer (A) and subsequently treating (A) with a post crosslinking agent, where before or during the polymerization, at least one water insoluble metal sulfate is added. Independent claims are also included for: (1) use of a water insoluble metal sulfate for preparing (I); (2) a water absorbing polymer particle comprising at least one monopolymerized ethylenic unsaturated, acid group containing monomer, which is partially neutralized, at least one mono polymerizable crosslinker, optionally one or more copolymerizable monopolymerized ethylenic and/or allylic unsaturated monomer, optionally one or more water soluble polymer (which is partially grafted) of the monomers, at least one reactable crosslinker and at least one monopolymerized water insoluble metal sulfate, where at least one metal sulfate is distributed in the polymer particle; and (3) a sanitary article comprising the water absorbing polymer particle.
