Homo‐ and copolyimides with high molecular weight could be synthesized from three dianhydrides and three diamines following two different one‐step methods. Solubility behavior with structural effect, viscosity, kinetics of solution imidization, synthesized method, mechanical and thermal properties, and effect of azeotroping agent are discussed. Results indicate that homo‐and random copolyimides were only prepared from a one‐step method; on the other hand, copolyimide with different arrangement, such as random, block, and alternating, could be synthesized by a modified one. © 1996 John Wiley & Sons, Inc.
