Abstract
An aqueous dispersion containing a water-insoluble, essentially electrically non-conductive, organic polymer as cation-active particles wherein a substantial portion of the cation-activity is provided by isothiouronium cations may be obtained by various methods including emulsion polymerization of hydrophobic monomers using an isothiouronium surfactant or by emulsion copolymerization of a monomer containing isothiouronium groups with hydrophobic monomers.
