摘要：
1. A process for producing water absorbent polymer particles, comprising the steps of (i) preparing an aqueous monomer solution containing at least partially neutralized monoethylenically unsaturated monomers bearing groups (α1) carboxylic acids, and at least one crosslinking agent (α3) ( ii) optional addition of fine particles of water absorbing resin or water solutions of salts to the aqueous monomer solution (iii) adding to the aqueous solution of the polymerization initiator, the monomer or at least one component of the system INIT polymerization tori which contains two or more components (iv) lowering the aqueous oxygen content monomers (v) loading the aqueous monomer solution to the reactor-the polymerizer (vi) the polymerization of monomers in an aqueous solution of the monomers in-polymerizer reactor (vii) unloading polymer gel strand from the reactor polymerizer, optionally grinding the polymer gel, thereby obtaining a polymer gel particles (viii) drying the polymer gel particles (ix) grinding the dried particles of the polymer gel to obtain thus dust-water absorbing polymer particles (x) by the size of ground water absorbing polymer particles and (xi) surface crosslinking milled and sorted by size of water absorbing polymer particles, wherein step (xi) the process comprises the steps of: (x1a) mixing the particles with an aqueous solution of a crosslinking agent and (x2a) heat treatment of the mixture obtained in step (x1a) process functioning in a horizontally mixing device, wherein a horizontal mixing device is operable hydraulic privod.2. A method according to Claim. 1,1. Способ получения частиц абсорбирующего воду полимера, включающий в себя стадии(i) получения водного раствора мономера, содержащего по меньшей мере частично нейтрализованные моноэтиленненасыщенные мономеры, несущие группы (α1) карбоновой кислоты, и по меньшей мере один сшивающий агент (α3)(ii) необязательного добавления мелких частиц водоабсорбирующего полимера или водных растворов соле
