New alicyclic Polyimides (PIs) were prepared from asymmetric alicyclic dianhydride, 5-(2,5-dioxotetrahydrofuryl)-3-methyl-cyclohexane-1,2-dicarboxylic anhydride (DOCDA) and the corresponding aromatic diamines such as p-phenylenediamine, m-phenylenediamine and oxydianiline etc. by the polycondensation in N-methyl-2-pyrrolidone (NMP) followed by chemical imidization as well as one step polyimidization in m-cresol in the presence of isoquinoline as a catalyst. The resulting PIs with glass transition temperatures ranging from 220 to 328 ℃ had the inherent viscosities within the range of 0.25 ∼ 1.42 dL/g. These polymers were readily soluble in aprotic polar solvents such as NMP, dimethylacetamide (DMAc), dimethylesulfoxide (DMSO), etc. Furthermore, some of the polymers showed good solubility properties to comon organic solvents like tetrahydrofurane and chlorform. Also, all of these polyimide films were tough, almost colourless, and transparent.
