This work reports the development of nitrodisplacement reactions between catechol and nitrophthalodinitriles, thus providing a bis(ether anhydride) and high-molecular-weight, thermally stable poly(ether imide)s with ortho-linked units. These polymers are far more soluble and more readily processable than corresponding polymers with para- and meta-linked diol units.
