## Abstract A soluble polyimide was synthesized from 2,2′‐bis[4‐(3,4‐dicarboxyphenoxy)phenyl]propane dianhydride (BPADA) and 3,3′‐dimethyl‐4,4′‐diaminodiphenylmethane (DMMDA) by a two‐step method, and it had good solubility both in strong bipolar solvents and in common low‐boiling‐point solvents. T
An imide ring-performed dicarboxylic acid bearing one hexafluoroisopropylidene and two ether linkages between aromatic rings, 2,2-bis[4-(4-trimellitimidophenoxy)phenyl]hexafluoropropane (II), was prepared from the condensation of 2,2-bis[4-(4-aminophenoxy)phenyl]hexafluoropropane and trimellitic anh
Alicyclic polyimides were prepared from 3-carboxylmethyl-cyclopentane-1,2,4-tricarboxylic acid dianhydride and conventional aromatic diamines. These polyimides possess good solubility in strong polar solvents, such as N-methyl pyrrolidone, N,N-dimethyl acetamide, N,N-dimethyl formamide, and m-cresol
