Assignee:

Cognis Corporation - Gulph Mills PA

International Classification:

C08J 302

US Classification:

524501

Abstract:

An aqueous dispersion containing a polyamide and non-polyamide polymer is prepared by dissolving the polyamide in an organic solvent with a surfactant to form a polyamide solution. Water is then added to the polyamide solution to form an aqueous dispersion. The non-polyamide polymer can be added before or after the addition of water. The polyamide/non-polyamide dispersion can be used to produce an ink with better adhesion to plastic substrates and reduced blocking problems.

International Classification:

C08K 300

US Classification:

524608

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.

US Classification:

523404

Abstract:

Self-dispersing curable epoxy resin ester dispersions prepared by a process comprising reacting a self-dispersing curable epoxy resin based on a polyoxyalkyleneamine with a fatty acid selected from the group consisting of drying oil and semi-drying oil fatty acids, are provided. The self-dispersing curable epoxy resin is based on a polyoxyalkyleneamine. Thus, a polyoxyalkyleneamine was present as a chemical precursor of the epoxy resin or a starting material therefor. The self-dispersing curable epoxy resin ester of the invention is in the form of an aqueous dispersion. When dried, films of the self-dispersing curable epoxy resin ester dispersion are useful as a coating composition.
