Method for Producing Water-Absorbent Polymer Particles by the Polymerization of Droplets of a Monomer Solution

摘要

A process for producing water-absorbing polymer particles by polymerizing droplets of a monomer solution in a surrounding gas phase, the resulting polymer particles having a water content of at least 5% by weight, and being aftertreated thermally in the fluidized state in the presence of steam at a temperature of at least 60° C.
