Abstract: A process for the reduction of the concentration of methoxyhydroquinone (MEHQ) in acrylic acid that is neutralized to 75-100% comprises continuous adsorption on activated carbon. An Independent claim is included for a process for the production of superabsorbers (I) by reduction of the MEHQ content by the novel process followed by polymerization, optionally with non-neutralized acrylic acid with optionally surface cross-linking.

Abstract: Disclosed is a water absorbing agent which consists of (a) particles of a water absorbing polymer and (b) a polymer which contains nitrogen and which contains 5-17 mol/kg protonated nitrogen atoms in relation to the overall weight of said nitrogen- -containing polymer. The inventive agent has an improved property profile with a high absorption capacity, improved fluid transmissibility and high water resistance.

Abstract: A process for producing sodium acrylate polymers by free-radical polymerization of sodium acrylate with or without other monomers in an aqueous medium, which comprises using sodium acrylate in the form of an aqueous solution or dispersion obtainable by dissolving or dispersing solid sodium acrylate in an aqueous medium. The polymers thus obtainable have an improved color number and a lower residual monomer content than conventional comparable polymers.

Abstract: Disclosed is a process for postcrosslinking a water absorbing polymer by the polymer being treated with at least one postcrosslinker and postcrosslinked and dried during or after the treatment by raising the temperature, the at least one postcrosslinker being a cyclic carbamate or a cyclic urea, wherein the cyclic carbamate or the cyclic urea was obtained by reacting respectively an aminoalcohol or a diamine with a cyclic carbonate.
