METHOD FOR PRODUCING WATER-ABSORBENT POLYMER PARTICLES WITH A HIGHER PERMEABILITY BY POLYMERISING DROPLETS OF A MONOMER SOLUTION
The invention relates to a method for producing water-absorbent polymer particles with a higher permeability by polymerising droplets of a monomer solution in a gas phase surrounding the droplets. A water-insoluble inorganic salt is suspended in the monomer solution and the polymer particles have an average particle diameter of at least 150 µm.
