ABSTRACT:
A method for the solventless synthesis of a phthalimide or phthalimide mixture is provided comprising contacting at least one amine reactant and at least one anhydride reactant in a solventless environment at a first temperature sufficient to allow the reactants to at least partially condense; and increasing the temperature to a second temperature sufficient to melt the reaction mixture, thereby allowing the reaction to go essentially to completion and form the reaction product.
