By the polycondensation reaction of 3,3’-dimethyl-4,4’-diaminodiphenylmethane and a mixture of an aliphatic dianhydride, bicyclo[2.2.2]-oct-7-ene-2,3,5,6-tetracarboxylic dianhydride (BOCA), and an aromatic one, benzophenonetetracarboxylic dianhydride (BTDA), taken in various molar ratio, have been synthesized aliphatic-aromatic polyimides. All the obtained compounds have been characterized in terms of solubility, inherent viscosity, and film forming ability, thermal stability, optical and mechanical properties..
