WATER-ABSORBING MATERIAL HAVING A COATING OF ELASTIC FILM-FORMING POLYMERS

摘要

The present invention relates to a water-absorbing material obtainable by a process 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 00C to 500C and b) heat-treating the coated particles at a temperature above 500C. and also to a process for its production.
