Abstract (en)
[origin: WO2011061282A1] The invention relates to a method for producing water-absorbent polymer foams by polymerization of a foamed aqueous monomer solution or suspension, containing an ethylenically unsaturated monomer, which bears acid groups and can be at least partially neutralized, the solution or suspension further containing a crosslinking agent, a photoinitiator, and a surfactant.
