• poly(amide-imide)s
• nitrile groups
• high thermal stability
• mechanical properties

Aromatic poly(amide-imide)s with flexible linkages have been synthesized by solution polycondensation reaction of two aromatic diamines containing nitrile groups, namely 2,6-bis(m-aminophenoxy)benzonitrile and 2,6-bis(p-aminophenoxy)benzonitrile, with trimellitic anhydride chloride. The polymers were easily soluble in polar organic solvents, such as N-methyl-pyrrolidinone, N,N-dimethylacetamide, N,N-dimethylformamide, and dimethylsulfoxide, and exhibited remarkable film forming ability. The thin films prepared by casting polymer solutions onto glass plates were transparent and flexible. The polymers showed high thermal stability, with decomposition temperature being above 400 degrees C. They exhibited a reasonable interval between glass transition and decomposition temperature, which can be advantageous for their processing. The physical properties such as mechanical and dielectric characteristics of these polymers were studied.
