Disclosed herein is a composition comprising a compatible blend of i) 24 to less than 84.5 weight percent of a linear poly(arylene sulfide), ii) 14 to 75 weight percent of a polysiloxane/polyimide block copolymer; and iii) 0.1 to less than 2.5 weight percent of a polymeric compatibilizer having 2 or more epoxy groups per molecule. Weight percent is based on the total weight of the composition. An article made from the composition has tensile elongation greater than or equal to 60% as determined by ASTM D638 and a Notched Izod impact strength greater than 50 joules per meter as determined by ASTM D256 at room temperature.

Blends of polysiloxane/polyimide block copolymer and poly(arylene sulfide)

A flame retardant composition and method for making flame retardant articles. The flame retardant composition can include a silicone polyetherimide, an fibrillated polytetrafluoroethylene, and a zinc borate. The silicone polyetherimide can be present in an amount of from about 99.6 to about 80.0 percent by weight. The silicone polyetherimide can have from about 5 to about 50 percent by weight dimethyl siloxane units, and less than about 100 ppm amine end groups. The fibrillated polytetrafluoroethylene can be present in an amount of from more than about 1.25 to about 5.0 percent by weight. The fibrillated polytetrafluoroethylene can be encapsulated in a polystyrene, a poly(styrene acrylonitrile), a poly(methyl methacrylate), a polycarbonate, a polyetherimide, a polysulfone, and combinations thereof. The zinc borate can be present in an amount of more than 0 to about 10 percent by weight.

Silicone polyimide compositions with improved flame retardance

An electrical wire comprising a conductor and a covering disposed over the conductor. The covering comprises a thermoplastic composition. The thermoplastic composition comprises a blend of an aromatic polyketone and a polysiloxane/polyimide block copolymer. The composition can further comprise one or more additives.
