Abstract
The invention relates to powdery, water-soluble, cationic polymer composition comprising at least two different cationic polymers, namely a first cationic polymer and a second cationic polymer, which differ in chemical nature and molecular weight, as well to a method for producing such powdery, water-soluble, cationic polymer composition, and to its use for promoting flocculation in solid-liquid separation, for example as a retention aid in paper manufacture, and in sludge dewatering/wastewater purification.
