Abstract
31P NMR and 1H NMR spectra of copolyesters containing phosphorus compounds, obtained by ester-exchange reaction, were studied. Poly(ethylene terephthalate) was used as the main component and poly(hydroquinone phenylphosphate), poly[bis(4-hydroxyphenyl)sulfonephenylphosphate], and poly[bis(4-hydroxyphenyl)sulfonemethylphosphate], as phosphorus compounds. The sequence distribution can be elucidated by 31P NMR as well as 1H NMR, and two polyesters become to random distribution by ester-exchange reaction between two polyesters.
