摘要：

A series of ternary-copolymer of fluorinated polyimides (FPIs) based on 1,4-bis-[4-amino-2-(trifluoromethyl)-phenoxy] tetrafluoride benzene (ATPT) and 1,4-bis-[4-amino-2-(trifluoromethyl)-phenoxy] benzene (BATB) were synthesized via atwo-step imidization with diamines and dianhydrides. All of the synthesized FPIs were characterized by FT-IR, H-1-NMR, GPC, XRD, TGA, UV-vis spectroscopy, and moisture uptakes tests. It was determined that all of the FPIs derived from ATPT possessed higher thermal stability with the 10% weight loss ranged from 463 to 508 degrees C, higher optical transparency with the cutoff wavelengths of 354-386nm and lower moisture uptakes in the range of 0.61-0.72% compared with the one based on BATB. In addition, the results showed that the fluorination of benzene exerted an important influence on the enhancement of solubility, thermal stability, moisture resistance, and optical properties of the FPIs.
