摘要:
A study was performed on organosoluble and light-colored fluorination polyimides based on 1,2-bis(4-amino-2-trifluoromethylphenoxy)benzene and aromatic dianhydrides. The polyimides were characterized by excellent thermal stability and good mechanical property. The results showed that they exhibited better solubility, lighter color and lower dielectric constant than corresponding nonfluorinated polyimides.
