Abstract
The invention relates generally to a process for the preparation of water-absorbent polymer particles, comprising the process steps including of drying the polymer gel particles wherein in process step (viii) the gel particles obtained in process step (vii) are charged onto the surface of the belt material of a belt dryer at a position L0 and are subsequently dried on their way through the belt dryer and wherein the belt material has been cooled before coming into contact with the gel particles. The invention also relates to water-absorbent polymer particles obtainable by such a process.
