  • Aqueous composition
    Patent number: 6376600
    Abstract: Aqueous dispersion of copolymers formed by the polymerization of a monomer mixture containing 0.05% to less than 4.5% by weight of certain terminally unsaturated oligomers are useful for improving the scrub resistance, corrosion resistance, opacifying capacity and/or efflorescence resistance of a coating.
