Abstract:
The present invention relates to a process for producing a water-absorbing material comprising the steps of a) spray-coating water-absorbing polymeric particles with an elastic film-forming polymer in a fluidized bed reactor in the range from 0° C. to 1500° C. and b) heat-treatment of the coated particles at a temperature above 50° C., wherein in step a) and/or b) an antioxidant is added and the water-absorbing material obtainable by this process.
