Abstract: The invention relates to a method for producing water-absorbing polymer particles having a high swelling rate and high permeability by polymerizing an aqueous monomer solution or monomer suspension to form an aqueous polymer gel, wherein a thermal blowing agent, which is substantially free of inorganic acid anions, is mixed into the polymer gel, and subsequently thermally drying the polymer gel.
