| titleOfInvention | Method for preparing polyetherimide and polyetherimide prepared by the method |
| abstract | A method for preparing an isolated polyetherimide composition, comprising combining a synthesized polyetherimide containing a unit of formula (I) and a melt-stabilizing amount of tri(C 8-30 acyl) glycerides, formula The anhydride of (II) or a combination comprising at least one of the foregoing to provide a mixture; and isolating the polyetherimide composition from the mixture to provide an isolated polyetherimide composition having within 30 minutes Complex viscosity change measured at 390°C, shear rate 6.28 rad/s, strain = 5%, and nitrogen is +15% to -20%, preferably from +10% to -20%, more preferably from +5 % to ‑20%. |
