TITLE ORDERED POLYETHERKETONES ABSTRACT OF THE DISCLOSURE Ordered copolymers of tere- and isophthalyl halides with diphenyl ether where the phthalyl groups alternate or where the terephthalyl or isophthalyl groups are in blocks are disclosed. These novel ordered copolyetherketones exhibit a higher level of crystallinity and more rapid crystallinity behavior than corresponding random copolyetherketones. They also form completely miscible blends with certain aromatic polyetherimides, which may be used in applications of composite and injection molded parts or films, depending on the proportions of copolyetherketones and polyetherimides.
