This paper reviews methods of synthesis of dianhydrides for use in poly(ether imide) syntheses. It discusses the synthesis of new dianhydrides from alkyl-substituted diols, catechol and its derivatives and dihydroxynaphthalenes and the synthesis of new poly(ether imide)s from them. The major features of the properties of these groups of polymers, especially those of highly processable poly(ether imide)s, are discussed and potential applications are considered.
