| titleOfInvention | Polyetherimide composition, method of manufacture, and articles formed therefrom |
| abstract | A method for producing a polyetherimide composition comprising: optionally in the presence of a solvent, using a compound selected from the group consisting of guanidinium salts, pyridinium salts, imidazolium salts, tetrakis(C6‑24) aryl ammonium salts, tetrakis (C7‑24 aryl alkylene) ammonium salt, dialkyl heterocycloaliphatic ammonium salt, dialkyl quaternary ammonium salt, (C7‑24 aryl alkylene) (C1‑16 alkyl) phosphonium salt, The catalyst of (C6-24 aryl) (C1-16 alkyl) phosphonium salt, phosphazenium salt and their combination catalyzes the reaction of dianhydride and organic diamine. |
