ABSTRACT:
Water-dispersible but water-insoluble vinyl polymers composed of at least 40 mol percent of hydrophilic cationic linkages, at least 5 mol percent of hydrophobic linkages and up to 10 mol percent of hydrophilic anionic linkages are flocculating agents for the solids in industrial effluents (including raw and digested sewage). The polymers form stable dispersions in water, and are employed in that state.
