Abstract:
1D spectra and 2D spectra of two polyester samples are measured by NMR.The analysis resu lts of the spectra are allowed to specify the composition and structure of the two samp es,which cannot beidentified by other methods. NMR enables asimple way to analyze polyester samples and obta in the vitalstructure information.
Key words:

摘要： 利用核磁共振 ( NMR)波谱仪的一维和二维技术对两种聚酯样品分别进行测试,通过对各种谱图的综合分析,不仅得到两种聚酯的组成, 还得到它们的结构序列, 这是用其他分析方法所无法得到的。用核磁共振法分析聚酯样品,不仅方法简单,而且可以获得非常重要的结构信息。
