The process according to the invention for producing an absorbent polymer has a first mixing event, in which a plurality of absorbent polymer particles (1) are mixed with a liquid (2) and a second mixing event, in which the liquid (2) is homogenized within the interior of polymer particles, wherein the polymer particles (1) in the first mixing event are mixed with a speed such that the kinetic energy of the individual polymer particles (1) is on average larger than the adhesion energy of the individual polymer particles (1), and the polymer particles (1) in the second mixing event are stirred at a lower speed than in the first mixing event. The different speeds effect a fluidisation of the polymer particles (1), which prevents a clumping of the polymer particles (1) during the mixing event. The absorbent polymers thus produced or a composite or a chemical product, comprising a polymer of this sort, are distinguished by a particularly rapid swelling behaviour. |
