Synthesis and properties of polyimides based on 4,4'-diaminotriarylmethanes and pyromellite dianhydride

Year: 2025

Type: article

Abstract: Polyimides based on 4,4’-diaminotriarylmethanes and pyromellitic dianhydride have been synthesized. Their solubility, thermal and mechanical properties have been studied. It is shown that the solubility of polyimides is associated with the free internal rotation of the triarylmethane fragment around the central carbon atom of the methane group and with the eff ect of the bulky side phenyl substituent in the initial diamine. It has been established that the thermal and mechanical properties of polyimides depend on the structure of the initial diamine.
