Light stable aliphatic thermoplastic urethane elastomers and method of making same
摘要：
An improved light stable polyether/polyol based aliphatic urethane thermoplastic elastomer prepared from reacting inter alia a polyol having low terminal end unsaturation and an organic diisocyanate. The elastomer is characterized by ultra violet stabilizer being present in a range of 0.25% to 2.0% at a total concentration of 1.0% to 2.0%, an antioxidant being present at a total concentration of 0.10% to 1.0%, and colorants/pigment being present in a total concentration in a range from 1.0% to 2.05% to produce an elastomer capable of withstanding Xenon arc artificial weathering with DE≦3.00 after 2450 kilojoules of exposure.
摘要（中）：

由特别是具有低端部不饱和部分的多元醇与有机二异氰酸酯反应制备的改进的光稳定性聚醚/多元醇基脂肪族聚氨酯热塑性弹性体。 弹性体的特征在于紫外线稳定剂的总浓度为1.0〜2.0％，抗氧化剂的总浓度为0.10〜1.0％，着色剂/颜料为 以1.0％至2.05％的范围内的总浓度存在，以产生在2450千焦耳暴露后DE <= 3.00的能够承受氙气弧人造风化的弹性体。
