Various soluble polyimides with bis[4-(3-aminophenoxy)phenyl]sulfone and three kinds of dianhydrides were prepared in a polar N-methyl-2-pyrrolidone solvent by the traditional chemical two-step method. All the polymers synthesized had good solubilities in polar solvents and excellent thermal propert

Soluble polyimides were synthesized and characterized from two diamines and four dianhydrides by the two-and the one-step method. Most of the polyimides could be soluble by one-step method except โฃ,โฃะˆ-bis(4-aminophenyl)-1,4-diisopropyl benzene/3,3ะˆ,4,4ะˆ-benzophenonetetracarboxylic dianhydride system
