Abstract
Binders comprising the association of chlorinated vinyl resins and quaternary ammonium salts are resistant to corrosion, fouling, and organisms in an aqueous medium. The binders are obtained by substituting the chlorines of the polymer with a molecule having a primary or secondary amine function and a tertiary amine function, and then quaternizing the tertiary amine function by an alkyl halide. The binders thus obtained are useful in the production of coatings resistant to fouling and organisms present in an aqueous medium, of bacterial anticorrosion coatings and coatings with fungicidal properties.
