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.

Abstract:
A composition for thickening aqueous based personal care products is comprised of a cosolvent selected from the group consisting of a diol, the mono alkyl ether of a diol, a salt of a sulfated ethoxylated alcohol, a salt of a sulfated ethoxylated alkyl phenol, and a complex organic phosphate ester; water; a nonionic surfactant and, an ester of an ethoxylated polyol.

International Classification:
C08L 6302
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.
Air-drying, water-reducible, acid-functional polyurethanes are obtained by reacting: (i) a fatty amide diol obtained by the reaction of a fatty acid or fatty acid derivative and an N,N-dialkanol amine; and (ii) a diisocyanate; and (iii) an acid-functional compound which also has two active hydrogen groups, other than acid groups, which are reactive with the diisocyanate.
