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

Key words: Polyetherinide, Chain structure, NMR spectroscopy Chemical shift correlationspectroscopy
