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