Abstract
A process for producing water-absorbing polymer particles by polymerizing droplets of a monomer solution, where the monomer solution comprises at least two initiators, one of the initiators is a peroxide with the exception of persulfate, and the molar ratio of peroxide to further initiator is at least 1:8, the water-absorbing polymer particles themselves, and hygiene articles comprising these water-absorbing polymer particles.
