Abstract
The effect of temperature, the order and duration of the interaction of terephthaloyl chloride (0.5 mol) and 3,3',4,4'-diphenyl ether tetracarboxylic acid dianhydride (0.5 mol) with 9,9-bis(4-aminophenyl)fluorene or 2,2'-bis(trifluoromethyl)benzidine (1.0 mol) in NMP on the properties of the resulting polyamide-imides was studied. The molecular weights and yields of the resulting polymers were shown to vary in a wide range (Mw = 64–438 kDa, yields 85–97%) and depend on the reaction conditions. The polyamide-imides obtained possess high heat resistance (Tg = 260–360 °C), thermal stability (T10% ~ 500 °C) and form high-strength films (σ = 122–160 MPa, E = 1.3–1.9 GPa, ε = 9–30%).
