Abstract: A water-based sulfonated polyurethane composition and footwear manufactured using the composition as as an adhesive, coating and primer. The sulfonated polyurethane is a reaction product ofa) at least one polyisocyanate;b) at least one alkylene diol;c) at least one sulfonated polyester polyol wherein the sulfo groups thereof are present as alkali metal salts; andd) at least one dihydroxy carboxylic acid, or salt thereof. The composition may also be modified to include a dispersed polymer or copolymer of an ethylenically unsaturated monomer. Such mofified compositions may be obtained by preparing the sulfonated polyurethane in the presence of an ethylenically unsaturated monomer and subsequently subjecting the mixture to free-radical polymerization conditions.

Abstract: A process for the preparation of sulfonated polyurethane-urea polymers, which are useful film to film laminating adhesives for flexible packaging in which the urethane-urea polymer component has no amide linkages. The water-based sulfonated polyurethane prepolymers are processed at reduced temperatures and are substantially free of volatile and/or leachable contaminants.

Abstract: Sulfonated polyester polyols and mixtures of sulfonated polyester polyols and hydroxy carboxylic acids are used to prepare improved aqueous anionic poly(urethane/urea) dispersions with a high crystallization rate, low heat activation temperature, high green strength, stability at low pH, which show good compatibility with other water based polymers and with crosslinkers. The aqueous anionic poly(urethane/urea) dispersions have high heat resistance after curing or blending with a crosslinker.

Abstract: A process for preparing poly(urethane/urea) prepolymers and aqueous poly(urethane/urea) dispersions (PUDs) therefrom, the poly(urethane/urea) polymers having high heat resistance and good water resistance. The method employs a water soluble volatile organic solvent, such as acetone, at a level of 0.1-5%, based on final dispersion weight, a level which does not require removal for purposes of flash point considerations.

Abstract: Aqueous dispersion adhesives of anionic polyurethanes which have high heat resistance and low activation temperature, even when employed without addition of a crosslinker. The polyurethane is the reaction product of an isocyanate terminated polyurethane prepolymer, and water. The polyurethane prepolymer is the reaction product of a polyol component and a diisocyanate component, the polyol component including:a sulfonated polyester polyol,a hydroxy carboxylic acid of the formula:(HO).sub.x R(COOH).sub.ywherein (R) represents a straight or branched, hydrocarbon radical containing 1 to 12 carbon atoms, and x and y represent values from 1 to 3, and optionally,a low molecular weight aliphatic diol having a molecular weight of from 60 to 400a non-sulfonated polyol,and the diisocyanate component being selected from the group consisting of aromatic diisocyanates, isopherone diisocyanate, hexamethylene diisocyanate and mixtures thereof.
