    摘要: Polymer blends and copolymers made therefrom, of anhydride-functionalized polyphenylene ether and polyetherimide. The components of the blends have improved compatibility, resulting in more homogeneous blends. The blends exhibit good mechanical properties and are suitable for forming films, molded products and other useful articles of manufacture. The copolymers have utility as compatibilizers for blends of polyphenylene ether and polyetherimide.

    摘要: Disclosed are blends of (a) a polyetherimide and (b) a minor amount of an acrylate copolymer of C.sub.1 -C.sub.5 acrylate and C.sub.1 -C.sub.5 methacrylate. These blends have a higher impact strength than that associated with the polyetherimide component of the blends. In addition, the blends exhibit improved extrusion and molding performance characteristics over those of the polyetherimide component of the blend when molded alone.

    摘要: A method is provided for making polyetherimides, based on the use of certain organic diamine catalysts, for example, 4-dimethylaminopyridine and secondary or tertiary aliphatic diamines, to accelerate the intercondensation of aromatic bis(ether anhydride) and organic diamine under solution or melt polymerization conditions. The resulting polyetherimides are high performance injection moldable thermoplastics.
