Abstract:
Molded articles having a maximum thickness of 3 centimeters and including a polyetherimide composition are described. The polyetherimide compositions include 60 to 99.9 weight percent of a polyetherimide having a weight average molecular weight of 5,000 to 80,000 Daltons, and 0.1 to 40 weight percent of an aryl phosphate having a molecular weight from 500 to 1,200 Daltons, wherein weight percent is based on the total weight of the composition. The compositions have a melt flow at least 10% greater than the melt flow of the same polyetherimide composition without the aryl phosphate, measured according to ASTM D1238 at 337° C. under a 6.7 kilogram load.

Abstract:
A polyetherimide-siloxane composition including 70 to 99.9 weight percent of a polyetherimide-siloxane copolymer having a weight average molecular weight of 5,000 to 80,000 Daltons and having a polysiloxane content of 10 to 50 weight percent, preferably 15 to 40 weight percent, more preferably 20 to 35 weight percent, and 0.1 to 30 weight percent of an aryl phosphate having a molecular weight from 500 to 1,200 Daltons, wherein weight percent is based on the total weight of the composition, is disclosed. The composition has a melt flow at least 10% greater than the melt flow of the same polyetherimide-siloxane composition without the aryl phosphate, measured according to ASTM D1238 at 300° C. under a 5.0 kilogram load.
