摘要：

The present invention relates to a process for producing water-absorbent polymer particles by polymerizing droplets of a monomer solution in a surrounding heated gas phase and flowing the gas cocurrent through the polymerization chamber, which comprises coating the water-absorbing polymer particles with at least one sulfinic acid, sulfonic acid and/or salts thereof.
