Abstract: | Poly(amino-p-benzoquinone)amides were indirectly prepared by low-temperature polycondensation of 2,3,5,6-tetraamino-p-hydroquinone, with terephthaloyl, isophthaloyl, or phthaloyl dichloride and subsequent oxidation of the obtained poly(amino-p-hydroquinone)amides. Then the poly(amino-p-benzoquinone)amides were converted by cyclodehydration with heating to the corresponding poly(p-benzoquinono)diimidazoles. The prepared redox thermally stable polymers were characterized by elemental analysis, UV, and IR spectral study, inherent viscosity solubility, and thermal analysis (DSC, TGA). The synthesis and properties of the corresponding model compounds are also reported. |
