摘要：
The microstructure of Poly(Ethylene Terephthalate) (PET) has been studied by 1H-NMR spectroscopy. Hexafluoroisopropanol(HFIP)-d2/chloroform-dl(CDCl3) (1/25 vol/vol) mixture as a solvent of PET for NMR mesurement is used. From the analysis of 1H-NMR spectrum. We can determine many different types of irregular structures of PET quantitatively as follows; Diethylene glycol and Triethylene Glycol. Ethylene Glycol and Diethylene Glycol terminal groups. Methyl ester group.
