用傅里叶变换红外光谱(FTIR)衰减全反射谱(ATR)研究了四种模型嵌段聚氨酯。这四种模型嵌段共聚物是聚氨酯—氨酯、聚脲—氨酯、聚氨酯—脲、聚脲—脲。讨论了这些模型化合物的特征谱带,N—H键及氢键的情况.
Four model block polyurethanes were investigated by Fourier transform infrared spectroscopy (FTIR) attenuated total reflectance spectroscopy (ATR). The four model block copolymers are polyurethane-urethane, polyurea-urethane, polyurethane-urea, polyurea-urea. The characteristic bands, N-H bonds and hydrogen bonds of these model compounds are discussed.
