New polyamideimides containing a bicyclo[2.2.2]octene ring in their main chains were synthesized by the method of low temperature solution polymerization of various diamines with N, N'-bis[p- (chlorof ormyl) phenyl] bicyclo [2.2.2] oct-7-ene-2, 3; 5, 6-bis (dicarboximide) [1]. The thermal stabilities as well as solubilities of the polymers obtained were investigated. Inherent viscosities of these polymers are 0.24-0.43g·dl-1 (in 0.5 gg·dl-1 DMF solution, at 25± 0.01°C). Most of these polymers are soluble in such an organic solvent as DMF, DMA, DMSO or mcresol. On the basis of the thermal analyses, it was found that all these polymers decompose at 360-400°C in air. However, the thermal stabilities of polymers obtained from [1] and aromatic diamines are superior to those obtained from [1] and aliphatic diamines
