摘要: 本文通过56.4MHz19F的核磁共振波谱对全氟聚甲乙醚的结构进行了初步研究。根据谱图上所出现的21条共振吸收峰,基本上确定了各峰的归宿。并在仪器分辨率所能达到的情况下,分别归纳出全氟聚甲乙醚不同单元组的序列分布,同时对聚合物链的未端结构也进行了探讨。

Abstract: A study is described for the structural determination of polyperfluoro me-thylether with 56.4 MHz 19F NMR spectra. The assignments of 21 fluorine resonance lines and the sequence distribution of the polymer are given. A brief discussion about the end group structure is also included.
