POWDERY, WATER-SOLUBLE CATIONIC POLYMER COMPOSITION, METHOD FOR THE PRODUCTION AND USE THEREOF

摘要

The invention relates to powdery, water-soluble cationic polymers containing at least two chemically different composed calionic 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.
