摘要：

Two diamine monomers 2-tert-butyl-1,4-bis(4-nitro-2-trifluoromethylphenoxy)benzene and 1,4-bis(4-amino-2-trifluoromethylphenoxy)benzene were reacted with the alicyclic dianhydride monomers 1,2,3,4-cyclobutanetetracarboxylic dianhydride to synthesize the poly(amic acid)s, and then obtain the corresponding polyimide films through thermal imidization. The structure and properties were characterized by fourier transform infrared spectroscopy (FT-IR), ultraviolet visible spectroscopy (UV-vis), thermogravimetic analysis (TGA), solubility test and so on. The effect of introduction of bulky tert-butyl and trifluoromethyl to the polyimide backbone on the properties of polyimide films was investigated. The experimental results showed that polyimides with tert-buty group exhibit excellent solubility, but their thermal and optical properties decreased slightly.
