    • The invention relates to improved polyurethane ionomers and methods for making the same. It was found that the polyurethane anionomers obtained by using the method of the invention had improved physical properties than those made by conventional methods. For example, the polyurethane ionomers produced by the method of the invention exhibit a plateau in the plot of elasticity modulus (as log10E′) vs. temperature over a useful and relatively broad temperature and frequency range. The polyurethane ionomers have nearly temperature-independent elasticity over a 50° C. range in the region of ˜−20 to +75° C. Another advantage is that the polyurethane ionomers of the invention are optically clearer than the conventionally prepared polyurethane ionomers. A further advantage of the invention is that the synthetic process of making the polyurethane ionomers is much faster than the known process for equivalent compositions. Additionally, striking tensile strength properties were observed for the polyurethane ionomers.
    • 本发明涉及改进的聚氨酯离聚物及其制备方法。 发现通过使用本发明的方法获得的聚氨酯阴离子聚合物比通过常规方法制备的那些具有改进的物理性能。 例如,通过本发明的方法制备的聚氨酯离聚物在弹性模量(作为对数10E')相对于有用且相对较宽的温度和频率范围内的温度曲线表现出平稳。 在约-20至+ 75℃范围内,聚氨酯离子交联聚合物在50℃范围内几乎具有独立于温度的弹性。另一个优点是本发明的聚氨酯离聚物比常规制备的聚氨酯离聚物光学清洁。 本发明的另一个优点是制备聚氨酯离聚物的合成方法比已知的等效组合物方法快得多。 此外,对于聚氨酯离聚物,观察到显着的拉伸强度特性。
