聚醚酰亚胺（YS－30）链结构的1D和2DNMR谱分析

THE ANALYSIS OF ONE AND TWO DIMENSION SPECTRA OF POLYETHERIMIDE （YS-30）

聚醚酰亚胺（ＹＳ－３０）是一种可溶性的聚酰亚胺，本文对它的￣（１３）ＣＮＭＲ谱，￣１ＮＮＭＲ谱和ＣＯＳＹ谱进行了研究．经过分析，对￣（１３）ＣＮＭＲ和￣１ＨＮＭＲ谱作出了归属，确认了聚醚酰亚胺的链结构．

Polyetherimide（YS-30）is one of the soluble polyimides. This paper presents the re-sults of our study on its ^(13)C NMR，~1H NMR，H-H COSY and C-H COSY spectra. Onthis basis the assingments of these spectra are very satisfactorily obtamcd。 Hence thechain structure of the polymer has been recongnized clearly。
