发明名称 Method of preparing inorganic pigment dispersions
摘要 <p>A polymer useful as an inorganic pigment dispersant is provided. The polymer is derived by polymerization of monomers consisting essentially of an ethylenically unsaturated aromatic monomer, an ethylenically unsaturated dicarboxylic acid monomer, and an ethylenically unsaturated monocarboxylic acid monomer. The monomers are polymerized in the presence of a mercapto-functional compound. The total amount of said ethylenically unsaturated acid monomers is sufficient to permit said polymer to associate with an inorganic pigment in an aqueous medium in a manner which disperses said inorganic pigment in said aqueous medium to form a stable aqueous dispersion of said inorganic pigment, and the amount of said ethylenically unsaturated aromatic monomer is sufficient to reduce the water sensitivity of a dried coating of a latex paint comprised of said stable aqueous dispersion of said inorganic pigment. A process of preparing a polymer useful as an inorganic pigment dispersant and a method of preparing an inorganic pigment dispersion useful in the preparation of latex paints are also provided.</p>
