Abstract: 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.

Abstract: Defoamers are the products of the reaction of epichlorohydrin and compounds having the formula (II) R3(EO)n(PO)mOH, wherein R3 is an alkyl, alkenyl or arenyl group having from 4 to 22 carbon atoms; a substituted alkyl or alkenyl group having from 4 to 22 carbon atoms wherein; n is a number from 0 to 50 and m is a number from 0 to 10; wherein the mole ratio of epichlorohydrin to (II) is from about 0.60/1 to about 2/1 are extremely efficient defoamers for aqueous surfactant systems. The defoamers are added to a surfactant in an amount sufficient to reduce or eliminate foam and have the advantage of being totally dispersible in water, are readily biodegradable, contain no organic solvents and do not affect the detergency of surfactants with which they are used because they are nonionic surfactants in themselves.
