Abstract (en)
[origin: WO2006133850A1] The invention relates to a method for producing powdery high-molecular weight water-soluble polymers for use in solid/liquid separating processes. The invention particularly relates to a method for modifying and drying inverse polymer dispersions with the aid of kneading technology while recovering the used solvent.
