Dianhydrides of alicyclic tetracarboxylic acids were synthesized by chemical modification of tri‐cyclodecenetetracarboxylic dianhydride and its chloro‐containing derivatives. By polycondensation of these di‐anhydrides with diamines polyimides were obtained. Thermal and thermooxidative degradation of these polyimides are discussed. By the interaction of polyamic acid carboxylic groups with diamines in presence of phosphorus pentoxide a number of polyimidoamidines have been synthesized, some physico‐chemical properties of them are studied.
