    摘要： 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.
