Abstract
Described is a process for producing water-absorbing polymers wherein a base polymer A is contacted and mixed with an aqueous additive solution B in a mixing device, wherein the base polymer A is formed from monomers bearing at least 30% neutralized acid groups and the aqueous additive solution B is dosed into the mixing device without nozzle via a pipe.
