Abstract

A new sulfone ether amide diamine was synthesized via three steps, starting from reaction of 4-aminophenol with 4-nitrobenzoyl chloride in the presence of propylene oxide afforded N-(4-hydroxy phenyl)-4-nitrobenzamide (HPNB). In the next step, reduction of nitro group resulted in preparation of 4-amino-N-(4-hydroxy phenyl) benzamide (AHPB). Final step in the preparation of diamine was the reaction of AHPB with bis(4-chlorophenyl) sulfone in the presence of K2CO3. All the materials were characterized using conventional spectroscopic methods. Poly(sulfone ether amide amide)s were synthesized by polycondensation reactions of prepared diamine with different diacid chlorides (aromatic and aliphatic ones). The obtained polymers were fully characterized and their physical properties including thermal behavior, thermal stability, solubility, and inherent viscosity were studied.
