Abstract
Several telechelic compounds were prepared by terminal functionalization of poly(oxyethylene) diacid via the reaction of the carboxylic groups with different aromatic amines. Starting from the telechelic diacid, the corresponding diacid chloride was prepared with thionyl chloride after which the compound was allowed to react with aniline, 2-naphtylamine, and 2-aminoanthracene. The telechelic products were characterized by UV/Vis, 1H-NMR, 13C-NMR, and IR spectroscopy. The UV/Vis spectrometric data were compared to those of the corresponding amines. In addition, refractive indices and solubility characteristics were also determined. In addition, the spectroscopic data were compared with respect to increasing terminal chain extension by the three aromatic compounds.
