Abstract
Poly(amides) (PAs) derived from bis(4-aminophenyl)-diphenylgermane and bis(4-aminophenyl)-diphenylsilane, and terephthaloyl, isophthaloyl, and tetrachloroterephthaloyl chlorides, were synthesized in N, N-dimethylacetamide solution. The products were characterized by IR and NMR spectroscopy. The results were in agreement with the proposed structures. The yields were almost-quantitative for PAs derived from terephthaloyl and isophthaloyl chlorides. However, the yields from the diacid tetrachloroterephthaloyl chloride were very low due to low reactivity. The inherent viscosity values of all PAs measured in o-chlorophenol were very similar. Thermogravimetric analysis indicated that the Ge-containing PAs were more stable than were those containing Si due to the higher polarity of the C–Si bond. The PAs derived from tetrachloroterephthaloyl chloride are exceptions owing to the influence of the chlorine atoms. The glass transition temperatures (T g) were determined for all the PAs. The PAs derived from the Si-containing diamine have a value higher than that for the Ge-containing diamine.
