A bis(ether amine) containing the ortho-substituted phenylene unit and pendant tert-butyl group, 1,2-bis(4-aminophenoxy)-4-tert-butylbenzene, was synthesized and used as a monomer to prepare polyimides with six commercial dianhydrides via a conventional two-stage procedure. The intermediate poly(ami
