New fluorinated polyimides have been synthesized by the reaction of 2,2'-bis(trifluoromethyl)-4,4'-diaminobiphenyl (TFDB) with 2,2-bis(3,4-dicarboxyphenyl)hexafluoropropane dianhydride (6FDA) or pyromellitic dianhydride （PMDA）。来自TFDB反应的聚酰亚胺6FDA/TFDB与6FDA的反应具有高光学透明度和高溶解度，例如N，N-二甲基乙酰氨酰胺（DMAC），四氢呋喃（Tetrahydrofuran（THF），THF），乙酸），乙酸乙酸酯和乙酸乙酯。此外，在1 MHz时，其低介电常数为2.8，低折射率为1.556，在589.3 nm时为1.556，低吸收率为0.2％。从TFDB与PMDA的反应制备的聚酰亚胺PMDA/TFDB不仅低介电常数为3.2，低折射率为1.647，而且还具有-5 x 10（-6）的低热膨胀系数（CTE）。学位-C-1。
New fluorinated polyimides have been synthesized by the reaction of 2,2'-bis(trifluoromethyl)-4,4'-diaminobiphenyl (TFDB) with 2,2-bis(3,4-dicarboxyphenyl)hexafluoropropane dianhydride (6FDA) or pyromellitic dianhydride (PMDA). The polyimide 6FDA/TFDB from the reaction of TFDB with 6FDA has high optical transparency and high solubilities in several solvents such as N,N-dimethylacetamide (DMAc), tetrahydrofuran (THF), acetone, and ethyl acetate. In addition, it has a low dielectric constant of 2.8 at 1 MHz, a low refractive index of 1.556 at 589.3 nm, and a low water absorption rate of 0.2%. The polyimide PMDA/TFDB prepared from the reaction of TFDB with PMDA has not only a low dielectric constant of 3.2 and a low refractive index of 1.647, but also a low coefficient of thermal expansion (CTE) of -5 x 10(-6) degrees-C-1.
