SYNTHESIS AND PROPERTIES OF HYDROPHILIC POLYMERS .4. PREPARATION AND CHARACTERIZATION OF POLY(OXYETHYLENE) TELECHELICS WITH DIFFERENT AROMATIC TERMINI

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.
