    Abstract: The present invention relates to a method of identifying in a fluid by measuring the amount of optical rotation the fluid causes in a beam of polarized light. The invention further provides for the use of an optional optically active marker in the fluids in order the impact the amount of rotation the fluid will cause. The invention provides a convenient and reliable means for identifying the fluid before, during and/or after the fluid's use.

    Abstract: The disclosed technology provides thermoplastic polyurethane compositions having non-leaching antimicrobial properties while still maintaining good physical properties, methods of making the same, and articles, including medical devices, made from such compositions. The disclosed technology includes a process of making an antimicrobial polymer composition, where the process includes mixing an antimicrobial additive into a polymeric material; wherein said polymeric material comprises a polymeric backbone made up of urethane linkages derived from a polyisocyanate and a polyol; and wherein said mixing occurs under conditions that result in the breaking of a minority of said urethane bonds resulting in reactive isocyanate groups; and wherein two or more of said reactive isocyanate groups react with said antimicrobial additive to covalently bond said antimicrobial additive into the polymeric backbone of said polymeric material; resulting in an antimicrobial polymer composition.

    Abstract: The thermoplastic polyurethane compositions described herein have very good recovery properties, rebound resilience, or both, while also having good softness (i.e. low 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 soft 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，同时具有良好的柔软性（即低硬度）。 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，同时也需要柔软的材料，并且在一些实施方案中为低雾度和/或良好的透明度。
