摘要：: 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 850 μm, to obtain a monomer solution mixed with fines；wherein the mixing in process step ii) is effected in a mixer (1) in which a first stream (2) of the fines and at least one further stream (3) of the monomer solution are passed from different directions simultaneously to a rotating mixing tool (4).本發明係關於一種製造吸水性聚合物結構體之方法，該結構體係以含酸基團之單體為基質，該方法包含以下方法步驟：i)　提供一單體溶液，其係包含視需要經部分中和之含酸基團之單體；ii)　混合該單體溶液與粉體以獲得一混有粉體之單體溶液，該粉體之至少達90重量%係由粒徑小於850微米之顆粒構成，以該粉體之總重量計；其中該方法步驟ii)之混合係於一混合器(1)中施行，其中一第一粉體流(2)及至少一額外之單體溶液流(3)係由不同方向同時流至一旋轉混合工具(4)。
