High flow polyetherimide compositions, and articles made therefrom

A reinforced polyetherimide composition, comprising

• 50 to 99.9 weight percent of a polymer composition comprising a polyetherimide having a weight average molecular weight of 5,000 to 80,000 Daltons;
• 10 to 40 weight percent of a reinforcing filler;
• 0.1 to 10 weight percent of flow promoter, wherein the flow promoter comprises an aromatic phosphate, a phosphazene, or a combination comprising at least one of the foregoing;
• 0 to 20 weight percent of a liquid crystalline polymer;
• wherein weight percent is based on the total weight of the reinforced polyetherimide composition;
• and
• wherein the reinforced polyetherimide composition has
• a melt flow rate (MFR), measured according to ASTM D1238 (2015) at 337° C. under a 6.7 kgf load, that is at least 10% higher than that of the same reinforced polyetherimide composition without the flow promoter, and
• a capillary melt viscosity, measured according to ASTM D3835 (2015) at a shear rate of 5000 l/s and a temperature of 380° C., that is at least 10% lower than that of the same reinforced polyetherimide composition without the flow promoter.
