Abstract
The invention relates to powdery, water-soluble cationic polymers containing at least two chemically different composed cationic polymers. A first cationic polymer is formed in the presence of a second cationic polymer from the monomer constituents in an aqueous solution according to the aqueous gel polymerisation method. The invention also relates to the use of said products in solid/liquid separation.
