摘要： 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.
摘要翻译：提供了可用作无机颜料分散剂的聚合物。聚合物通过基本上由烯键式不饱和芳族单体，烯键式不饱和二羧酸单体和烯属不饱和单羧酸单体组成的单体的聚合衍生而来。单体在巯基官能化合物的存在下聚合。所述烯属不饱和酸单体的总量足以允许所述聚合物以水性介质中的无机颜料与分散所述无机颜料在所述水性介质中以形成所述无机颜料的稳定的水分散体的方式缔合，所述烯键式不饱和芳族单体的量足以降低由所述稳定的所述无机颜料的水分散体组成的乳胶漆的干燥涂层的水敏感性。还提供了可用作无机颜料分散剂的聚合物的制备方法和制备用于制备乳胶漆的无机颜料分散体的方法。
