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.
