A kind of viscous polyamic acid(PAA) solution was prepared by polycondensation reaction between fluorinated diamine II and pyromellitic dianhydride(PMDA) in polar aprotic organic solvent DMAc,and the corresponding polyimide(PI) film was also obtained by thermal imidization.The properties of the PI film were further studied,and compared with PI(PMDA-ODA).The experimental results show that the fluorinated diamine improves the transparency and solubility of PI and maintains an excellent thermal stability of PI.
