Abstract
The kinetics of sedimentation of aqueous kaolin dispersion in the presence of multicomponent flocculating additives was studied. Binary and ternary mixtures based on poly-1,2-dimethyl-5-vinylpyridinium methyl sulfate, poly-N,N-dimethyl-N,N-diallylammonium chloride, and poly-N,N,N-trimethyl-N-methacryloyloxyethylammonium methyl sulfate were used as flocculants. The synergistic effect of the cationic polyelectrolytes in such multicomponent systems was revealed.
