Abstract: Process for producing aqueous compositions of water-soluble polymers from aqueous polymer gels by comminuting and mixing the aqueous polymer gel with an aqueous liquid by means of a comminution unit comprising a flow-chamber, a sheet-like molding tool and rotating cutting means, wherein a stream of an aqueous liquid flows through the flow chamber, aqueous polymer gel is pressed through the sheet-like molding tool, cutting the thus formed gel strands into slices, dispersing them in the aqueous liquid and homogenizing the thus obtained mixture.
