Novel organosoluble polyimide based on an asymmetric bis(ether amine): 3, 4′-Bis(4-aminophenoxy)-benzophenone

A new kind of asymmetrical ether diamine, 3,4′-bis(4-aminophenoxy) benzophenone (BABP), was synthesized from the nucleophilic substitution reaction of 4-chloronitrobenzene and 3,4′-dihydroxybenzophenone in the presence of potassium carbonate, followed by catalytic reduction with SnCl 2·6H2O and concentrated hydrochloric acid. The prepared diamine was employed in the preparation of a novel polyimide containing asymmetrical diaryl ether segments via the polycondensation of it with BTDA by a two-step method. The resulting polyimide exhibits excellent solubility, film-forming capability and high thermal resistance.
