A polyetherimide resin is described herein. The resin includes a structure of repeating units of the formula (I)
wherein each aromatic ring in the structure can be substituted with at least one halogen atom, nitro group, cyano group, alkyl group, cycloalkyl group, or aryl group. Another embodiment relates to a method for preparing a polyetherimide polymer. The method includes the step of reacting metaphenylenediamine bis(4-nitrophthalimide) with a bisphenolic mixture of a salt of bisphenol A and a salt of an arylcyano-modified bisphenol.
