厚度为0.25英寸的聚碳酸酯挤出片其0.22口径FSP(碎片模拟射弹)V-50冲击速度为925英尺/秒。V-50是速度测量值，在此速度下50％的22口径射弹射穿0.25英寸厚的聚碳酸酯片，进入放置在该聚碳酸酯片背面6英寸处的20毫米厚2024 T6铝板(参考片材)。
美国专利3,866,242(在此引为参考)公开了一种聚氨酯聚合物防护罩。所述聚氨酯是如下制得的：
(a)使分子量约为700-1000的聚醚二醇或聚酯二醇与亚甲基二(环己基异氰酸酯)以约三个NCO对一个羟基的当量比进行反应，形成预聚物；
(b)以0.90-1.04 NH2/1.0 NCO的当量比使所述预聚物与两个芳环之间具有亚甲基桥的芳香胺固化剂(如4，4’-亚甲基二(2-氯苯胺))反应。
美国专利4,808,690(在此引为参考)公开了一种由多元醇固化的预聚物制得的透明聚氨酯聚合物。所述预聚物是由多异氰酸酯和至少一种多官能含羟基的中间体制得的。
美国专利4,208,507公开了一种挠性聚氨酯-脲弹性体，它是使：(A)由分子量为600-10,000的主要二官能的多羟基化合物与至少一个NCO基团连接在脂环结构上的有机二异氰酸酯反应，其用量使得OH∶NCO的总比例为1∶1.2-1∶10，得到的预聚物与(B)3，3’，5，5’-四甲基-4，4’-二氨基二苯基甲烷反应制得的，A与B反应的摩尔比约为1∶0.8-1∶1.2。
发明的概述
本发明光学透明的聚氨酯可如下制得：使重均分子量约为400-2000的一种或多种聚酯二醇、聚己内酯二醇、聚醚二醇或者聚碳酸酯二醇与脂环族二异氰酸酯以约2.5-4.0个NCO比一个OH的当量比进行反应，先制得预聚物。随后使该预聚物与芳香二元胺固化剂(如二乙基甲苯二胺)反应，两者的当量比约为0.85-1.02NH2/1.0 NCO，较好约O.90-1.0 NH2/1.0 NCO，更好约O.92-0.96NH2/1.0 NCO。
本发明聚氨酯尤其适用于需要优良抗冲击性和高热变形温度的透明用途，例如建筑物窗玻璃、机动车窗玻璃、防暴盾、飞机座舱罩、面罩、挡板、眼镜和太阳镜、护目镜和透明装甲。
本发明的一个目的是提供透明的聚氨酯，与现有的材料相比它具有优良的光学透明度、优良的抗冲击性能、高的耐化学剂性和高的热变形温度。
本发明的另一个目的是提供一种低成本透明抗冲击聚氨酯用于商业用途。

制备本发明聚氨酯
本发明聚氨酯可用本领域已知的准预聚物法或全预聚物法制得。本发明聚氨酯的较好制备方法如下：以约2.5-4.0 NCO/1.0 OH，较好以约3.0 NCO/1.0 OH的当量比例先将二异氰酸酯与含OH的中间体相混合，随后在212-230°F使之反应3-5小时，或者在260-265°F反应5-10分钟，或者在275-290°F反应3-5分钟。随后移去热源，使预聚物冷却至约160°F，并在该温度稳定约24小时，接着测定预聚物中的NCO百分数。随后可加入附加的二异氰酸酯以达到确定的当量。接着以约0.85-1.02NH2/1.0 NCO，较好以约0.90-1.0 NH2/1.0 NCO，更好约0.92-0.96NH2/1.0 NCO的当量比在约160-180°F使预聚物与芳香二元胺固化剂反应。随后将预聚物在230-275°F固化4-24小时。在较低温度下固化时间较长，在较高温度下固化时间较短。
本发明聚氨酯聚合物可铸塑或模压。铸塑是较好的方法，因为它制得的聚氨酯聚合物具有最佳的光学特性。
可将预聚物和固化剂混合物铸塑在模具中，随后固化。可选择适当的固化时间和温度部分固化本发明聚氨酯材料，随后从铸塑模具中移出之，并制成所需的形状。使用这种方法，可将聚氨酯材料制成简单或复杂的形状，随后完全固化之。
可向预聚物中加入三元醇，其加入量足以产生约1％(按反应物的当量计)的交联，例如以总反应物重量计4-8％发生交联。适用于本发明的三元醇包括三羟甲基乙烷和三羟甲基丙烷。向预聚物中加入三元醇提高了热变形温度，并在某些情况下改进了固化聚氨酯的冲击性能。
在制造本发明聚氨酯时可使用各种抗氧剂、紫外光稳定剂、抗变色剂、光学增亮剂、和脱模剂。例如，按反应物总重量计可在预聚物中最多加入5％的一种或多种抗氧剂。适用于本发明的抗氧剂包括多官能位阻酚型抗氧剂。多官能位阻酚型抗氧剂的一个例子是购自Ciba Geigy的Irganox 1010，它的化学式如下：
还可在固化步骤前或固化过程中向预聚物中加入紫外光稳定剂，按反应物总重量计其加入量最多约为5.0％，较好约0.5-4.0％。适用于本发明的紫外光稳定剂包括苯并三唑。苯并三唑紫外光稳定剂的例子包括Cyasorb 5411和Tinuvin328。购自American Cyanamid的Cyasorb 5411具有下列化学式：

Figure C9881429900121
实施例I-VII
将脂环族二异氰酸酯与一种或多种聚酯二醇、聚己内酯二醇、聚醚二醇或聚碳酸酯二醇相混合。在干燥的氮气下将反应物加热至275-290°F，在该温度下保温3-5分钟，使之反应成预聚物。将该预聚物冷却至220-250°F，加入紫外光稳定剂、抗氧剂、抗变色剂和/或光学增亮剂。将预聚物进一步冷却至170-200°F，随后进行评价并在160°F储存24小时。测定NCO的百分数。
接着在160-180°F使该预聚物与芳香二元胺固化剂以0.85-1.02NH2比1.0NCO的当量比进行反应。接着将聚合物在230-275°F固化4-24小时。
