| Abstract: | Poly(amino-p-hydroquinone)amides prepared from 2,3,5,6-tetraamino-p-hydroquinone and adipic, suberic, or sebacic acid dichloride were converted by mild oxidation to the corresponding poly(amino-p-benzoquinone)amides. The latter, prepared also directly from 2,3,5,6-tetraamino-p-benzoquinone, were converted by thermal cyclodehydration to the corresponding thermally stable poly(p-benzoquinono)diimidazoles. The prepared new redox polymers were characterized by elemental analysis, UV and IR spectral study, inherent viscosity, solubility, and thermal analysis (DSC, TGA). |
