摘要:
Antistatic agents and their use in processing textiles or formed plastic substrates. The antistatic agent comprises a compound having a fluorocarbon moiety and an ethoxylated quaternary ammonium moiety. The antistatic composition increases the electrolytic conductivity of textile or plastic materials treated therewith, thereby increasing the rate of electrostatic charge dissipation thereof. The coatings remain effective after exposure of the treated substrate to an aqueous environment.

Antistatic agents and their use in natural or synthetic textiles or formed plastic substrates to enhance the surface resistivity thereof. The antistatic agent comprises a mixture of polyoxyalkylamine derivatives comprising a fluoro-acid moiety, a fatty acid moiety and a quaternary ammonium moiety. The coatings remain effective after exposure of the treated substrate to an aqueous environment and to elevated temperatures.

摘要:
A polymer useful as an inorganic pigment dispersant is provided. The polymer is derived from monomers consisting essentially of an ethylenically unsaturated aromatic monomer, an ethylenically unsaturated dicarboxylic acid monomer, and an ethylenically unsaturated monocarboxylic acid monomer. 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:
A process is provided for preparing a dispersion of a polyamide in water, said process comprising:forming a solution of a polyamide having an acid value of greater than about 2 in an organic solvent to form a solution of said polyamide in said solvent, said polyamide and said solvent being at a temperature below the softening point of said polyamide during said dissolving, said solution further comprising a surfactant, wherein at least a portion of the acid value of said polyamide is neutralized,adding sufficient water to said solution with mixing to form an oil-in-water dispersion, the temperature of said solution and said water being below the softening point of said polyamide during said adding, andremoving at least a major amount of said organic solvent from said oil-in-water dispersion. The resulting dispersion is useful in preparing a coating of the polyamide, which coating is useful as an adhesive.
