In this article a new synthesis of 3,3Ј-diaminobiphenyl (3,3Ј-DABP) is described, along with the preparation and characterization of polyamides and polyimides based on it. Reactivity of this monomer was calculated by a molecular simulation study, using ab initio quantum-mechanical methods. Terephtha

New aromatic polyamide and polyimides were prepared from di(aminopheny1)acetylenediurea. In addition, model compounds were synthesized and their IR spectra were in agreement with those of the corresponding polymers. The polymers were amorphous and readily soluble in polar aprotic solvents (DMF, NMP,
