Abstract:
A process for preparing water-absorbing polymer beads by polymerizing droplets comprising at least one monomer in a gas phase surrounding the droplets, the droplets being obtained by enveloping a first monomer solution with a second monomer solution and polymerizing the second monomer solution and polymerizing to give a more highly crosslinked polymer than the first monomer solution.
