    摘要： This technology relates to an integrated article that includes (a) a flexible foam region and (b) a non-foam region. The flexible foam region and the non-foam region are each made of a polyurethane composition. In some embodiments, the flexible foam region is a midsole, and wherein the non-foam region is an outsole. The flexible foam region is made from a flexible polyurethane injection molded foam. The non-foam region is made from a non-foamed polyurethane, which may be extruded or thermoformed. The invention relates to this integrated article, as well as the methods of making and using the same.

    摘要： A process of making a thermoplastic polyurethane by the reaction of (1) a hydroxyl terminated polyester intermediate, wherein the hydroxyl terminated polyester intermediate is comprised of repeat units that are derived from adipic acid and a glycol component comprising 1,3-propylene glycol, and said hydroxyl terminated intermediate has a number average molecular weight which is within the range of 500 to 10,000 Daltons, (2) a diisocyanate; and (3) a glycol chain extender. This thermoplastic polyurethane by this process is unique in that it has a greatly reduced tendency to bloom. This is highly desirable in applications where high clarity is desired because blooming causes articles containing the thermoplastic polyurethane to be hazy or foggy in appearance. Blooming can also reduce the ability of an article made with the thermoplastic polyurethane to be securely bound to another article with an adhesive.

    摘要翻译： 本发明公开了由（1）羟基封端的聚酯中间体，（2）聚异氰酸酯和（3）乙二醇增链剂的反应产物组成的热塑性聚氨酯; 其中羟基封端的聚酯中间体由衍生自1,3-丙二醇和二羧酸的重复单元组成; 其中所述羟基封端的聚酯中间体具有500至10,000的数均分子量; 并且其中所述热塑性聚氨酯包括作为所述聚异氰酸酯和所述乙二醇增链剂的反应产物的硬链段。 这种热塑性聚氨酯的独特之处在于其大大降低了开花倾向。 在需要高透明度的应用中，这是非常理想的，因为起霜使包含热塑性聚氨酯的制品在外观上模糊或雾化。 开花还可以降低用热塑性聚氨酯制成的制品用粘合剂牢固地粘合到另一制品上的能力。
