聚氨酯聚氨酯polyurethanes主链含—NHCOO—重复结构单元的一类聚合物。英文缩写PU。由异氰酸酯（单体）与羟基化合物聚合而成。由于含强极性的氨基甲酸酯基，不溶于非极性基团，具有良好的耐油性、韧性、耐磨性、耐老化性和粘合性。用不同原料可制得适应较宽温度范围（－50～150℃）的材料，包括弹性体、热塑性树脂和热固性树脂。高温下不耐水解，亦不耐碱性介质。常用的单体如甲苯二异氰酸酯、二异氰酸酯二苯甲烷等。多元醇分3类：简单多元醇（乙二醇、丙三醇等）；含末端羟基的聚酯低聚物，用来制备聚酯型聚氨酯；含末端羟基的聚醚低聚物，用来制备聚醚型聚氨酯。聚合方法随材料性质而不同。合成弹性体时先制备低分子量二元醇，再与过量芳族异氰酸酯反应，生成异氰酸酯为端基的预聚物，再同丁二醇扩链，得到热塑弹性体；若用芳族二胺扩链并进一步交联，得到浇铸型弹性体。预聚物用肼或二元胺扩链，得到弹性纤维；异氰酸酯过量较多的预聚体与催化剂、发泡剂混合，可直接得到硬质泡沫塑料。如将单体、聚醚、水、催化剂等混合，一步反应即可得到软质泡沫塑料。单体与多元醇在溶液中反应，可得到涂料；胶粘剂则以多异氰酸酯单体和低分子量聚酯或聚醚在使用时混合并进行反应。聚氨酯弹性体用作滚筒、传送带、软管、汽车零件、鞋底、合成皮革、电线电缆和医用人工脏器等；软质泡沫体用于车辆、居室、服装的衬垫，硬质泡沫体用作隔热、吸音、包装、绝缘以及低发泡合成木材，涂料用于高级车辆、家具、木和金属防护，水池水坝和建筑防渗漏材料，以及织物涂层等。胶粘剂对金属、玻璃、陶瓷、皮革、纤维等都有良好的粘着力。此外聚氨酯还可制成乳液、磁性材料等。
