Abstract
Abstract Blends of polyphenylene oxide resin with poly(ethylene-coorganic-acid-ester) resins provide thermoplastic compositions characterized by unique properties, particularly an unusually useful combination of high impact strength, high thermal stability, high tensile strength, and high elastic moduli. Such compositions are optionally modified through the inclusion of an alkenyl aromatic resin (e.g., polystyrene, etc.), to exhibit much improved melt processing characteristics in addition to high strength properties.
