Different polyimide resins were synthesized using N-[3-(2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl)phenyl]acetamide and the following compounds with terminal amino groups: urea, 6-aminohexylamine, 2-aminoethylamine, 3-[4-(3-aminopropyl)piperazin-1-yl]propan-l-amine, 4-[(4-aminocyclohexyl)methyl]cyclohexanamine, 4-(4-aminobenzyl)ani line, and 4-[-aminophenyl)sulfonyl] aniline. The thermal and thermooxidative behaviour of the polyimide resins was studied by thermogravimetric measurements (TG) in oxygen and nitrogen. Polyimide resins have been irradiated (500 kGy) and their radiation stability evaluated on the basis of thermal and thermooxidative behaviour of irradiated samples. (C) 2004 Elsevier Ltd.
