ABSTRACT:
Absorbent polymer granulate comprising the following process steps: i) polymerization of an aqueous monomer solution to obtain a polymer gel; ii) comminution of the polymer gel to obtain a gel granulate; and iii) drying of the gel granulate, and is characterized in that the gel granulate after step ii) has a spread behavior. The production process of an absorbent polymer distinguishes itself by a particularly efficient drying step iii), which enables a particularly gentle and uniform drying of the gel granulate. The obtained absorbent polymers and products and items produced therefrom have a particularly uniform product quality and constant physical-chemical properties.
