| Abstract | Synthesis and characterization of 4-acetoxybenzoic acid and 6-acetoxy-2-naphthoic acid, labelled with deuterium in the rings and with carbon-13 and oxygen-17 in the carboxyl-positions, and of the corresponding homo- and copolyesters, are described. Kinetic studies of high-temperature deuteration were performed on 6-hydroxy-2-naphthoic acid. Mass spectrometry provides information about the degree of labelling with H-2, C-13 and O-17. Composition and molecular weight of isotopically labelled polymers were monitored by H-1 NMR after digestion in basic methanol. The thermal behavior was investigated by differential scanning calorimetry and thermogravimetry. |
