| Abstract: | Viscous polyamic acid solution(PAA) was prepared by polycondensation reaction between 4,4'-bis(4-aminophenoxy) diphenyl sulfide(DADPSE) and various anhydride in polar aprotic organic solvent,and corresponding polythioetherimide(PI) film was also obtained by thermal imidization of PAA thin layer.The surface property and thermal stability of the film were further studied. |
