    摘要： A process is provided for preparing a dispersion of a polyamide in water, said process comprising: dissolving a polyamide having an amine 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 and an inorganic alkaline material, adding sufficient water containing an acid 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, the amount of said acid being sufficient to neutralize a portion of said inorganic alkaline material, but insufficient to coagulate said polyamide from the resulting oil-in-water dispersion, and removing 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.

    摘要： A polyamide resin comprising the reaction product obtained by the reaction of an acid component comprised of a major concentration of a dimer acid and minor concentration of a monobasic acid and an amine component comprised of a major concentration of a short-chain alkylenediamine, a first minor concentration of a medium-chain alkylenediamine and second minor concentration of a polyoxyalkylene diamine having a molecular weight greater than about 500 is provided. The polyamide resin is used to form a blend containing the polyamide in a major amount by weight and a first minor amount by weight of a polar wax and a second minor amount by weight of a polyolefin elastomer. The composition is used to reinforce a footwear upper, e.g. as a print on box toe material.

    摘要： An apparatus for filtering fluids such as air, oil, and water includes a filter (13) adhesively attached to a structural supports (16, 17) by means of an aqueous dispersion of polyamide resin (14, 15). The dispersion (14, 15) is applied between the filter (13) and structure supports (16, 17) and then dried under ambient conditions or in an oven to solidify the resin (14, 15) and fixedly bond the filter (13) to the structural supports (14, 15).
