Methods of producing thermoplastic poly(amide-urethane) block copolymers having excellent flexibility at low temperatures are provided. The methods comprise reacting substantially linear polyamides, the polyamides being based on dimerized fatty acids and terminated by carboxyl and/or amino groups and aliphatic or cycloaliphatic polyethers and/or reaction products thereof with 2,3-epoxypropanol. The reaction products contain substantially no free isocyanate groups or epoxide groups. The invention also relates to the use of these products as adhesives and corrosion inhibitors for metallic and/or wooden materials.

Methods of making and using thermoplastic block copolymers

Methods of producing thermoplastic poly(amide-urethane) block copolymers having excellent flexibility at low temperatures are provided. The methods comprise reacting substantially linear polyamides, the polyamides being based on dimerized fatty acids and terminated by carboxyl and/or amino groups and aliphatic or cyloaliphatic polyethers and/or reaction products thereof with 2,3-epoxypropanol. The reaction products contain substantially no free isocyanate groups or epoxide groups. The invention also relates to the use of these products as adhesives and corrosion inhibitors for metallic and/or wooden materials.

Method of making and using thermoplastic block copolymers

This invention is directed to thermoplastic polyamides and the preparation thereof. The thermoplastic polyamides, which are prepared by condensing (a) dimerized higher fatty acids and (b) monomeric fatty acids with (c) polyether diamines and (d) aliphatic or cycloaliphatic diamines, are useful in melt adhesive compositions.

Thermoplastic polyamide based upon dimerized fatty acid and polyether

The use of known thermoplastic polyamides based on dimerized fatty acids and predominantly aliphatic diamines, especially polyether diamines, as carriers for fragrances and perfumes.

Thermoplastic polyamide as fragrance carrier

This invention relates to adhesive composition. More particularly, this invention relates to adhesive compositions comprising polyamide (I) prepared by condensing dimeric higher fatty acids and monomeric fatty acids with polyether diamines and aliphatic or cycloaliphatic diamines and polyamide (II) prepared by condensing dimeric higher fatty acids and monomeric fatty acids with aliphatic or cycloaliphatic polyamines.

Method for providing corrosion protective coatings for metal surfaces. The coatings contain conventional coating components to which are added at least one zinc or lead salt of five- or six-membered heterocyclic compounds substituted by at least one hydroxyl or mercapto group and the ring includes at least one nitrogen atom and at least two conjugated double bonds, of which at least one has the formation. ##STR1## as corrosion inhibitors.

Method for providing corrosion resistance to metal objects

A water-dispersed film-forming vehicle suitable for lacquers is disclosed. The vehicle consists of an aqueous dispersion of an air-drying, low acid-number alkyd resin dispersed by the use of a nonionic surfactant consisting of an adduct of ethylene oxide units onto a phenolic compound substituted by a hydrophobic aliphatic radical containing olefinic double bonds, preferably, containing 12 to 18 carbon atoms and 1 to 5 double bonds. The adduct includes 5 to 40 ethylene oxide units per mol. The water-based dispersion diluent in which the alkyd resin is dispersed may include pigments, siccatives for the alkyd drying resin and optionally processing aid solvents.

Water-dispersed film-forming lacquer containing air-drying alkyd resins

A water-dispersed film-forming vehicle suitable for lacquers is disclosed. The vehicle consists of an aqueous dispersion of an air-drying alkyd resin dispersed by the use of a surfactant consisting of an adduct of allyl glycidyl ethers and ethylene oxide units onto a hydrophobic aliphatic radical having a replaceable hydrogen atom, optionally substituted by an aryl radical. The hydrophobic aliphatic radical may be a fatty-acid radical of from 6 to 26 carbon atoms and the aryl substituent is a phenol. The adduct includes 2 to 10 allyl glycidyl units and 5 to 25 ethylene oxide units per mol. The water-based dispersion diluent in which the alkyd resin is dispersed may include pigments, siccatives for the alkyd drying resin and optionally processing-aid solvents.

Aqueous dispersions of cross-linkable alkyd and/or amino resins, which contain reactive surface active compounds produced by addition of glycide and/or ethylene oxide to a starting compound having a hydrophobic aliphatic radical, optionally substituted by an aryl radical, which contains al least one labile hydrogen atom which can react with an epoxide, wherein the number of hydroxyl groups in said surface active compounds is between 2 and 30, are useful as coating agents or varnish binding agents.
