The present invention relates to a method for producing water-absorbing polymer particles, wherein the foamed monomer solution or suspension is polymerized, dried, pulverized, classified, and in a fluidized bed reactor within a range of 0 ° C to 50 ° C. The method comprises spray coating a film-forming elastic polymer onto the water-absorbing polymer particles and heat treating the coated particles at a temperature above 50 ° C. |
