Abstract
A method is provided for making aromatic ether imides in the substantial absence of a solvent. A mixture of at least one halo-substituted phthalimide and at least one anhydrous alkali metal phenoxide salt is heated at a temperature at least sufficient to convert the halo-substituted phthalimide to the molten state and below the temperature at which the alkali metal phenoxide is thermally unstable.
