Abstract: The thermoplastic polyurethane compositions described herein have very good recovery properties, rebound resilience, or both, while also having good hardness. It has been difficult to provide thermoplastic polyurethane compositions with this combination of properties. Some compositions described herein also provide low haze and/or good clarity properties. These combination of properties make the thermoplastic polyurethane compositions described herein useful materials for application that require fast recovery, good rebound resilience, or both while also requiring hard materials, and in some embodiments low haze and/or good clarity.

Abstract translation: 本文所述的热塑性聚氨酯组合物具有非常好的恢复性能，回弹性或两者，同时具有良好的硬度。 难以提供具有这种性质组合的热塑性聚氨酯组合物。 本文描述的一些组合物还提供低雾度和/或良好透明性。 这些性质的组合使得本文所述的热塑性聚氨酯组合物需要快速恢复，良好的回弹性或两者的应用的有用材料，同时也需要硬质材料，并且在一些实施方案中为低雾度和/或良好的透明度。
