Abstract:
A process for preparing polyimide resins comprises stirring a diamine and a dianhydride in a solvent to form a slurry; heating the slurry to a temperature sufficient for the diamine and dianhydride to react wherein the temperature is below the melting point of the dianhydride, below the melting point of the diamine, or below the melting points of the dianhydride and diamine; and reacting the diamine and dianhydride to form a polyimide having sufficient molecular weight to precipitate from the solvent.
