ABSTRACT:
A method for making a polyarylether block copolymer having amide functionality including reacting a dihydroxyaromatic compound having amide functionality and a dihaloaromatic sulfone or dinitroaromatic sulfone in the presence of a base to form a polyarylether having amide functionality and reacting the polyarylether having amide functionality with a polymer. The block copolymer and blends are also provided.
