摘要： Water-soluble polylactones and poly(lactone-urethanes) are disclosed. The polylactones are prepared by ring opening a lactone such as epsilon-caprolactone with a low equivalent weight active hydrogen-containing material having at least two active hydrogen groups per molecule selected from the class consisting of hydroxyl, primary amine, secondary amine and thiol, and having anionic water-solubilizing groups or groups which are readily reacted to form anionic water-solubilizing groups. The resulting polylactone can be combined with curatives such as amine-aldehyde condensates to form water-soluble coating compositions and can be reacted with polyisocyanates to form unique water-soluble poly(lactone-urethanes, ureas or thiolurethanes) which are also useful for coating applications.Surprisingly, it has been found that the polyurethanes prepared by reacting organic polyisocyanates with the novel polylactone adducts of the present invention and optionally low molecular weight diols are more water dispersible and form coatings with greater adhesion to the substrate and less water sensitivity than comparable polyurethanes prepared by reacting organic polyisocyanates with conventional polylactone diols and low equivalent weight active hydrogen-containing materials which also have anionic water-solubilizing groups.

摘要： Cured coatings having a high degree of extensibility, gloss retention, good sprayability and other desirable properties are obtained from compositions made by reacting (A) an organic polyisocyanate; (B) a hydroxy-containing material selected from the group consisting of saturated polymeric diols having low glass transition temperatures, saturated low molecular weight diols, and mixtures thereof; (C) a hydroxyalkyl ester of an ethylenically unsaturated carboxylic acid; (D) one or more copolymerizable monomers; and (E) a curing agent. These compositions, when used as coatings, are durable, adherent and highly flexible. The coatings are particularly useful on resilient and rubbery substrates such as EPDM rubber, foam rubber, polyurethane foam, and on metal surfaces, such as mild steel and aluminum.

摘要： A water-diluted, ungelled, non-sedimenting polyurethane and a process for preparing such a polyurethane in an aqueous medium is disclosed. High molecular weight thermoplastic products are obtained by chain extending in aqueous medium an NCO polymer having a salt group equivalent weight of 6000 or less and substantially free of reactive hydrogen. The average functionality and equivalent ratio of the polyisocyanate and active hydrogen-containing materials used in making the NCO polymer, as well as the functionality of the chain extender, are carefully controlled so as to get high molecular weight ungelled products. Thermosetting compositions can be made by adding curing agent to the chain extended material. Curing agents can also be incorporated into the polymer molecule either in the making of the partially reacted NCO-containing prepolymer or by further reaction with the partially reacted NCO-containing prepolymer. The water-dispersed polyurethanes of the present invention are excellent film formers, capable of making coatings with a wide spectrum of desirable properties. In addition, they can be added to other water-compatible compositions to improve flexibility, hardness, drying and other coating properties.

摘要： A water-diluted, ungelled, non-sedimenting polyurethane and a process for preparing such a polyurethane in the presence of water is disclosed. The polyurethanes are prepared so that they contain a high percentage of highly active hydrogens which enable the polyurethanes to be further reacted with a curing agent to form thermoset products. The polyurethanes of the present invention are prepared by first dispersing a partially reacted NCO-containing polymer in water, which is then chain extended with a material such as an organic diamine. Thermosetting compositions are made by adding curing agent to the chain extended material. Curing agents can also be incorporated into the polymer molecule either in the making of the partially reacted NCO-containing prepolymer or by further reaction with the partially reacted NCO-containing prepolymer. The water-dispersed polyurethanes of the present invention are excellent film formers, capable of making coatings with a wide spectrum of desirable properties. In addition, they can be added to other water-compatible compositions to improve flexibility, hardness, drying and other coating properties.
