Abstract: Disclosed herein is a composition comprising a poly(arylene sulfide); a polysiloxane/polyimide block copolymer; glass fiber and an optional platy filler. The polysiloxane/polyimide block copolymer has greater than or equal to 10 weight percent siloxane content, based on the total weight of the polysiloxane/polyimide block copolymer. The composition retains greater than or equal to 60% of the initial viscosity after being retained at 320° C. for 30 minutes and the composition has an OSU peak heat release less than 45 kW/m2 when measured using the method of FAR F25.4 and according to FAR 25.853 (d). Articles comprising the composition are also described.

Abstract: A method of manufacturing an isolated polyetherimide composition includes combining an as-synthesized polyetherimide comprising units of the formula (I) and a melt-stabilizing amount of a tri(C8-30 acyl) glyceride, an anhydride of the formula (II), or a combination comprising at least one of the foregoing, to provide a mixture; and isolating a polyetherimide composition from the mixture to provide the isolated polyetherimide composition having a change in complex viscosity measured over 30 minutes at 390° C., at a shear rate of 6.28 rad/seconds, strain=5%, and under nitrogen, from +15 to −20%, preferably from +10 to −20%, more preferably from +5 to −20%.
