Ke. Geckeler et N. Arsalani, SYNTHESIS AND PROPERTIES OF HYDROPHILIC POLYMERS .4. PREPARATION AND CHARACTERIZATION OF POLY(OXYETHYLENE) TELECHELICS WITH DIFFERENT AROMATIC TERMINI, Journal of macromolecular science. Pure and applied chemistry, A33(9), 1996, pp. 1165-1179
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.
