Paragraph 0065-0066; 0185-0186, (2021/09/04)
The invention belongs to the technical field of macromolecules, and particularly relates to spirobibenzoxazole diamine, a preparation method and application thereof, polyimide and a preparation method and application thereof. According to the present invention, the spiro-bis-benzoxazole diamine is adopted as the monomer to prepare the polyimide, and the spiro structure is introduced into the diamine structure, such that the obtained polyimide has excellent solubility and excellent processability; meanwhile, the polyimide forms a microporous structure, so that the gas permeability of the polyimide is improved.
