The present invention relates generally to a method for producing water-absorbing polymer particles, comprising the process steps: (i) obtaining an aqueous solution of a monomer containing at least one partially neutralized, monoethylenically unsaturated monomer containing carboxylic acid groups (α1), and at least one a crosslinking agent (α3); (ii) optionally adding fine particles of a water-absorbing polymer to the aqueous monomer solution; (iii) adding a polymerization initiator or at least one component of a polymerization initiator system, which contains two or more components, to an aqueous solution of a monomer; (iv) optionally reducing the oxygen content in the aqueous monomer solution; (v) loading an aqueous monomer solution onto a ribbon polymerization reactor; (vi) polymerization of monomers in an aqueous solution of monomer on a tape to form a polymer gel; (vii) discharging the polymer gel from a polymerization belt reactor and optionally crushing the polymer gel; (viii) drying the optionally crushed polymer gel; (ix) grinding the dried polymer gel to form water-absorbing polymer particles; (x) sorting the size of the crushed water-absorbing polymer particles; and (xi) optional surface treatment of the crushed and sorted water-absorbing polymer particles; where the tape has the shape of a gutter extending longitudinally at least 30% relative to the longitudinal length of the tape; where the chute contains the first part and the additional part.Настоящее изобретение, в целом, относится к способу получения водоабсорбирующих полимерных частиц, включающему технологические стадии: (i) получение водного раствора мономера, содержащего по меньшей мере один частично нейтрализованный, моноэтиленненасыщенный мономер, содержащий группы карбоновой кислоты (α1), и по меньшей мере один сшивающий агент (α3); (ii) необязательное добавление мелких частиц водоабсорбирующего полимера к водному раствору мономера; (iii) добавление инициатора полимеризации или по меньшей мере
