Abstract
Several telechelic compounds were prepared by terminal functionalizati on of poly(oxyethylene) diacid via the reaction of the carboxylic grou ps 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-naphtyl amine, and 2-aminoanthracene. The telechelic products were characteriz ed by UV/Vis, H-1-NMR, C-13-NMR, and IR spectroscopy. The UV/Vis spect rometric data were compared to those of the corresponding amines. In a ddition, refractive indices and solubility characteristics were also d etermined. In addition, the spectroscopic data were compared with resp ect to increasing terminal chain extension by the three aromatic compo unds.
