Abstract

Aromatic polyimides are known for their remarkable thermal and chemical properties which are greatly influenced by their precursors. In this study, we report synthesis and characterization of four different aromatic polyimides. The four different dianhydrides (ODPA, BTDA, BPDA and PMDA) were reacted with a diamine (BisAPAF) via azeotropic imidization under same conditions. FTIR analysis confirmed the formation of aromatic polyimides and all but one polyimide (HPIBPDA) were found to be completely soluble in common solvents. The obtained molecular weights were between 16,000-32,000 Da, glass transition temperatures were between 250-275°C, degradation temperatures were above 550°C and the d-spacing values were around 5Å. These properties are promising and can be beneficial for various applications such as thin films and membranes.
