Abstract: The invention relates to a method for producing water-absorbent resins, wherein a) acrylic acid is produced at an acrylic acid production site, b) the produced acrylic acid is dissolved in water at the acrylic acid production site, thus an aqueous acrylic acid solution is obtained, c) the acrylic acid solution is fed into a pipeline at the acrylic acid production site and is transported through the pipeline to an acrylic acid processing site d) the aqueous acrylic acid solution undergoes a radical polymerization at the acrylic acid processing site. Said method guarantees a save transport of the highly reactive acrylic acid. A threat caused by early polymerization, as with pure acrylic acid, is not possible, as the acrylic acid is 'diluted' due to the aqueous solvent and the specific thermal capacity or the evaporation enthalpy of the water limit the maximum temperature increase. The amount of polymerization inhibitors can be reduced or no polymerization inhibitors have to be used at all. Temperature control of containers, pipe conduits and pipelines, carrying the aqueous acrylic acid solution is not necessary, as the solidification point of the aqueous acrylic acid solution is lower than the one of the anhydrous acrylic acid.

Abstract: The invention relates to a method for producing water-absorbent polymer particles by the polymerisation of droplets of a monomer solution in a gaseous phase that surrounds said droplets and by the subsequent cross-linking of the polymer particles. According to the invention, the polymer particles that have been subsequently cross-linked are at least partially coated.
