Study of Polyurethanes(ureas) Pendant with Azo-dye

摘要: 用扩链法合成了一系列含有偶氮染料的侧基聚氨酯和聚脲。ＴＦ－ＩＲ、ＤＳＣ、ＤＭＡ的研究表明，聚合物有良好的力学性能，样品中软硬段的含量决定材料的物理性能。通过ＵＶ的测定，计算出样品均有较高的三阶非线性光学（ＮＬＯ）系数。

Abstract: Polyurethanes(ureas) pendant with different kinds of azo dye were synthesized by using azo dye diols or diamines as chain extender in a two step block copolymerization reaction. The polymers were characterized by FT IR, DSC, DMA, and UV. The samples ex
