摘要

process for preparing water-absorbing polymeric particles, water-absorbing polymeric particles, use of the polymeric particles, and hygiene article. a process for preparing high permeability water-absorbing polymer particles by polymerizing droplets from a monomer solution comprising acid group-containing monomers in a gas phase surrounding the droplets, wherein the monomer solution comprises polyvalent cations and the polymer particles have an average diameter of at least 150 µm.
