Abstract: Disclosed is a method for the continuous production of crosslinked, particulate, gel-type polymers by copolymerizing a) water-soluble, monoethylenically unsaturated monomers, b) 0.001 to 5 molar percent of monomers containing at least two polymerizable groups, the percentage being relative to the monomers (a), in a mixer. The substances that are added at the beginning of the kneader are conveyed in an axial direction towards the end of the mixer. The inventive method is characterized in that at least one of the following conditions is met: i) the filling level in the kneader mixer is at least 71 percent; ii) the water-soluble, monoethylenically unsaturated monomers contain up to 150 ppm of a semicyclic ether of a hydroquinone; iii) the temperature in the polymerization zone exceeds 65 °C; iv) the kneader has a remixing rate of less than 0.33.

CPC classification number: C08F220/06
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.
