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:

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。
