Synthesis of a Novel Diamine 4-[(4'-Butoxyphenoxy)carbonyl]-phenyl-3", 5"-diaminobenzoate and Corresponding Polyimides
摘要:
A novel diamine 4-[(4'-butoxyphenoxy)carbonyl]phenyl-3", 5"-diaminobenzoate (BCDA)was synthesized from 4-butoxyphenol, 4-hydroxybenzoic acid and 3, 5-dinitrobenzoic acid through four main intermediates, and a series of polyimides were also synthesized. All the intermediates and the final product were characterized by FTIR and 1H-NMR. The key step in synthesis route is selective hydrolyzation of two ester groups in 4-butoxyphenyl-4'-acetoxybenzoate, by adjusting the reaction temperature and the concentration of ammonia, shorteding the reaction time. The properties of the novel polyimides, such as the aggregation structures, glass transition temperature, solubility and the pretilt angles, were carried out.
