Abstract

Strong cationic polyelectrolytes in powder form based on acrylamide and quaternized or salified dimethylaminoethyl acrylate contain more than 50 mole % of the cationic units uniformly distributed along the copolymer chains. They are used for flocculating colloidal suspensions and/or coalescing emulsions, especially in sewage water purification installations.
