  • Dispersant for water-based solids-containing fluids and a drilling fluid
    Patent number: 4581147
    Abstract: The present invention provides a dispersant for water-based, solids-containing fluids comprising a copolymer of a sulfonated styrene monomer and a second monomer selected from the group consisting of maleic anhydride, maleimide, and dimethyl maleate, wherein the copolymer contains an amide formed on the second monomer. The amide can be formed on the second monomer by a reaction using a nitrogen source selected from the group consisting of ammonia, primary amines, and secondary amines.
