Abstract: The invention relates to a method for producing water-absorbing polymer particles with a higher permeability by polymerising droplets of a monomer solution in a gas phase surrounding the droplets. The monomer solution contains at least 0.5 wt %, in relation to the monomer, of a cross-linking agent and polymerisation takes place in the droplets in the homogeneous phase and the polymer particles have an average diameter of at least 150 µm.

Abstract: The invention relates to a method for producing water-absorbing polymer particles. According to said method, a monomer solution or monomer suspension, containing at least one unsaturated carboxylic acid, at least one semicyclic ether of hydroquinone and at least one inorganic peroxide, is polymerized and the polymer particles are coated with at least one basic salt of a bivalent metal cation.
