ABSTRACT:
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 crystallization and more rapid crystallinity behavior than corresponding random copolyetherketones. They also form completely miscible blends with certain aromatic polyetherimides.
