A method of preparing a thermoplastic polyurethane includes reacting specific amounts of a hydrogenated polydiene diol, a poly(alkylene oxide) diol, a chain extender, and a diisocyanate in the presence of a solvent. The thermoplastic polyurethane exhibits a desirable balance of tensile strength and tensile elongation. It is useful for fabricating foams, films, fibers, fabrics, coatings, adhesives, automotive instrument panels, power tool casings, casings for mobile electronic devices, sporting goods, clothing, footwear, gloves, condoms, and medical devices, among other articles. |
