摘要
对聚氨酯弹性体中氢键化的各特征基团的振动吸收峰进行了系统的归属。通过变温红外对其结构的研究表明：Ｎ－Ｈ振动区，羰基区和醚链区各特征基团吸收谱带的位置，峰形都会随温度的变化发生改变。ＦＴＩＲ对反应过程中反应基团ＮＣＯ吸收峰（Ｖ～２２７５ｃｍ－１）面积的减小，脲羰基峰面积的增加进行快速定量扫描跟踪，可以准确的研究反应动力学反应过程中形态的发展。ＦＴＩＲ在材料进行力学性能测试时，也是研究其结构变化的一个有力工具。
he characteristic bands with relation to hydrogen bonding in Polyurethane are assigned .Fourter transform infrared temperture studies of hydrogen bond in polyurethane Shows :The warenumbers and area of the characteristic bonds in N-H Stretching region and C=O Stretching region change,with the variations of tempertuer.Fourier-transform infrared spectral studies of kinetics and morphology development of polyurethane are performed ,with quantitative analysis of variations of VNCO2273cm-1and amide iregion.FTIR is also a valuable tool that stady the structure of PU,as its mechanic properties are measured.
