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
A series of polyimides were prepared by a solution polycondensation reaction between 3-carboxylmethylcyclopentane-1,2,4-tricarboxylic dianhydride and 4-alkyloxybenzene-1,3-diamines in N-methyl-2-pyrrolidone and chemical imidization with triethylamine and acetic anhydride. These polyimides possess gr
