ABSTRACT:
An aqueous dispersion of a polymer having a cationic charge on the surface of the polymer particles is used for treatment of fouled water. Said aqueous dispersion contains quaternary ammonium salt or inorganic or organic acid salt of a copolymer obtained by emulsion polymerization of, in the presence of a cationic surfactant, (a) 0.1 - 8.0% by weight based on total monomers of at least one .alpha.,.beta.-ethylenically unsaturated monomers containing basic nitrogen or at least one .alpha.,.beta.-ethylenically unsaturated monomers containing halogen and other (b) .alpha.,.beta.-ethylenically unsaturated monomers and/or (c) conjugate diene monomers, (b) and (c) being copolymerizable with said monomer (a). Said aqueous cationic dispersion is especially effective for treatment of fouled water containing anionic latexes.
