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.
