Summary:A method for the manufacture of a polyetherimide composition includes catalyzing the reaction of a dianhydride and an organic diamine with a catalyst selected from guanidinium salts, pyridinium salts, imidazolium salts, tetra(C6-24)aryl ammonium salts, tetra(C7-24 arylalkylene) ammonium salts, dialkyl heterocycloaliphatic ammonium salts, bis-alkyl quaternary ammonium salts, (C7-24arylalkylene)(Cl-16alkyl) phosphonium salts, (C6-24aryl)(Cl-16alkyl) phosphonium salts, phosphazenium salts and combin ations thereof, optionally in the presence of a solvent.
