We have investigated a novel monomer having a pendent phenyl imide group for preparing new cycloaliphatic-aromatic polyamides. Novel polyamides were synthesized by a direct polycondensation reaction of N-phenyl-2,3-imide cyclopentane-1,4-dicarboxylic acid (PCPA) and various aromatic diamines. A direct polycondensation was carried out by a Yamazaki's direct polycondensation that is typical of using triphenyl phosphite, lithium chloride, and pyridine. Inherent viscosity of these resulting polyamides was in the range 0.47-1.05 dL/g. The glass transition temperatures of these polyamides were in the range of 190-200°C. The decomposition temperatures of them were in the range of 310-323°C in nitrogen atmosphere. The Solubility of these polyamides are good in aprotic solvents such as DMAc (N,N-Dimethylacetamide), NMP (N-Methyl-2-Pyrrolidinone) and DMF (N,N-Dimethylformamide). Transparent, flexible, and tough films were cast from DMAc solutions.
