Abstract

A high‐temperature, high‐resolution ^13^C nuclear magnetic resonance spectroscopy technique was developed for the analysis of poly (p‐phenylene sulfide) (HT/HR NMR of PPS). This technique can be applied to the identification and quantitative analysis of end groups and polymer structure in high‐temperature polymers where solution temperatures above 200°C are required for analysis. Verification of calculated ^13^C NMR shift values of chloro‐terminated and hydrogen‐terminated end groups was made by HT/HR NMR of two oligo (p‐phenylene sulfide) model compounds. Identification of the chlorine end group was made in high‐molecular weight PPS. On the high‐molecular weight PPS, identification and quantitative analysis of amino and N‐alkylamino end groups were possible only after derivatization of the polymer with ^13^C‐enriched benzoyl chloride.
