Abstract:
The invention relates generally to a process for the preparation of water-absorbent polymer particles, including the process steps of preparing particulate water-absorbent polymer and mixing the particulate water-absorbent polymer with an aqueous crosslinker solution and heat-treating the mixture of particulate water-absorbent polymer in a horizontally operated mixing device, wherein the horizontally operated mixing device is hydraulically driven. The invention also relates to water-absorbent polymer particles obtainable by such a process.
