| 摘 要： | 采用高分辩率１ＨＮＭＲ，分析确定了脂肪醇环氧乙烷／环氧丙烷共聚醚的结构。以起始剂端甲基吸收峰形状和积分值为基准，根据吸收峰面积积分值与相应的氢核数目成正比的原则，确定共聚醚的起始剂为正丁醇，相对分子质量为８０２，ＥＯ／ＰＯ为５０．５／４９．５，并通过验证已知聚醚的结构，证明该方法是可行的。

| Abstract: | The structure of copolyethers of ethylene oxide and propylene oxide based on alkyl alcohol were determined by distinct 1 HNMR.According to the principle of integral of 1 H absorption peaks in proportion to the number of hydrogen nuclei,and based on the shape and integral of absorption peaks of chain starter's end methyl,the structural parameters of copolyethers such as chain starter,relative molecular mass and molar ratio of EO/PO were decided.The reliability of the method was tested and verified by determining copolyethers which structure was known.\= |
