Abstract

New poly(ether ether imide)s were synthesized based on an aromatic diamine containing pyridine and four ether groups. Diamine was designed to induce desirable properties to final polymer such as flexibility and processability in addition to thermal stability. The diamine was synthesized via a three-step procedure. Firstly, 1-fluoro-4-nitrobenzene was reacted with hydroquinone to obtain a nitrophenol compound. Next, the catalytic reduction was performed to convert nitro to amino group. Finally, the resulted aminophenol was reacted with 2,6-dichloropyridine and the diamine was synthesized. Polycondensation reactions of the diamine with three dianhydrides led to the preparation of novel poly(ether ether imide) films. All prepared materials and polymers were completely characterized. Thermal stability and glass transition temperature of polyimides were measured and compared. Mechanical properties and cross-section morphology of films were also investigated. Poly(ether ether imide)s revealed unique balance of physical and thermal properties including very high flexibility along with outstanding thermal stability.
