Polymer blends contain a polyphenylene ether and a siloxane-polyetherimide copolymer. These blends exhibit good ductility, good injection moldability, very low flammability and high impact strengths.

Polyphenylene ether/siloxane polyetherimide copolymer

Flame resistant polymer blends contain a polyetherimide and an impact strength-enhancing amount of a siloxane-polyetherimide copolymer. These blends exhibit high impact strengths, good blow-moldability and injection moldability, amenability to thermoforming and very low flammability. The blends are particularly suited to the manufacture of aircraft cabin interior components.

Flame resistant polyetherimide resin blends

Flame resistant polymer blends contain a polyetherimide and an impact strength-enhancing amount of a siloxane-polyetherimide copolymer and a solvent resistance-enhancing amount of a polycarbonate. These blends exhibit excellent impact strengths, high heat distortion temperatures, good solvent resistance, and amenability to blow-molding, injection molding and thermoforming operations. The blends are particularly suited to the manufacture of aircraft cabin interior components.

Ternary polymer blends contain (a) a polyetherimide, (b) a polycarbonate and (c) a minor amount of an acrylic rubber interpolymer composite. These blends are characterized by high impact strengths and advantageous processing temperatures.
