Process For Producing a Water-Absorbing Matieral Having a Coating of Elastic Film-Forming Polymers |
摘要 |
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 00 C to 1500 C and b) heat-treatment of the coated particles at a temperature above 50° C., wherein in step b) the duration of the heat-treatment is chosen that the CS-SFC value of the obtained polymeric particles is at least 10% of the optimum CS-SFC value, and the water-absorbing material obtainable by this process.
