A poly(amic acid) (PAA) was prepared by reaction of 4,4'-(hexafluoroisopropylidene)diphthalic anhydride (6FDA) and 2,2-bis(4-(4-aminophenoxy)phenyl)hexafluropropane (BAPP) in N,N-dimethylacetamide (DMAc). The cast films of the synthesized PAA were thermally treated at different temperatures to create polyimide (PI) films. The heat treatment temperature varied between 80 and 230 o C to investigate the imidization index in relation with the solvent evap- oration rates. The progress of PAA…
