<p>The present invention relates to a process for producing a water-absorbing polymer structure based on acid group-containing monomers, comprising the process steps of: i) providing a monomer solution comprising the optionally partly neutralized, acid group-containing monomer; ii) mixing the monomer solution with fines which consist at least to an extent of 90% by weight, based on the total weight of the fines, of particles having a particle size of less than 850μm, to obtain a monomer solution mixed with fines; wherein the mixing in process step ii) is effected in a mixer in which a first stream of the fines and at least one further stream of the monomer solution are passed from different directions simultaneously to a rotating mixing tool.</p> |
