ABSTRACT Polyimides are a class of well‐known high‐performance polymers combined the excellent mechanical, electrical, and thermal properties widely applied in many high‐tech fields. Traditional polyimides can only be processed state soluble intermediates with hazardous step cyclodehydration elimination nonvolatile polar solvent. Therefore, great effort has been devoted to development that full imidation state. The incorporation side groups into polyimide backbone is an efficient approach...

ABSTRACT A novel diamine monomer 1 , 4,4'‐(9 H ‐fluorene‐9,9‐diyl)‐bis(2‐ tert ‐butylaniline), was synthesized from 9‐fluorenone and 2‐ ‐butylaniline by the condensation reaction. Then it polymerized with several commercial aromatic dianhydrides, respectively, to produce polyimides (PIs) one‐pot method. The number‐averaged molecular weights of resulting PIs are in range (4.54–8.82) × 10 4 polydispersity indices 2.51 4.33 gel permeation chromatography measurement. They soluble many organic...
