A soluble copolyimide was synthesized via the conventional two-step method by using 3,3′,4,4′-benzophenonetetracarboxylic dianhydride(BTDA) as the dianhydride monomer,2,2-bis[4-(4-aminophenoxy)phenyl]propane(BAPP) and 4-phenyl-2,6-bis(4-aminophenyl)pyridine(PBAP) as the diamine.The structure and performance of polymer were characterized by FT-IR,1H NMR,XRD,viscosity testing,solubility testing and TGA.The results showed that the obtained polyimides had low-order aggregation.The inherent…
