采用质谱、紫外和核磁共振等手段，对偶氮型聚氧乙烯醚染料及其中间体进行了结构与发色状况研究，结果表明偶氮染料接枝聚氧乙烯醚链后，染料近似呈正态分析，为具有相似结构，不同环氧乙烷平均加成数的同系混合物，接枝聚氧乙烯醚链长短，对其紫外吸收影响很小，紫外最大吸收λmax基本不变。

A series of polyoxyethylene azo disperse dye and theirintermediates have been analyzed. Their structure and colour properties were stu d ied with mass spectrometry (MS), 1 H-nuclear magnetic reso n ance (NMR) and ultraviolet/visible (UV/VIS) spectra. MS spectra revealed that th e ethoxylated azo dyes were a mixture of compounds with similar body structure b ut differ in polyoxyethene chain length. From the results of MS spectr a, the degree of ethoxylation and distribution of dyes could be seen clearly. The maximum absorption wavelengths (λmax) provided very little effect as th e average EO number increases.
