Abstract (en)
[origin: WO2013117496A1] The invention relates to a method for producing water-absorbing polymer particles by polymerizing an aqueous monomer solution or monomer suspension, comprising at least one ethylenically unsaturated, acid-group-bearing monomer, which monomer is at least partially neutralized by adding a neutralizing agent, wherein the neutralizing agent is filtered before being added.
