Aromatic ether–ketone–‘X’ polymers. Part 2.—EK–Imide copolymers
Abstract
A modified Friedel–Crafts synthesis has been used to make two series of aromatic ether–ketone–imide copolymers. All the copolymers were semicrystalline and, in some cases, useful combinations of glass-transition temperature and melt temperatures were found. Some properties of the copolymers are reported and discussed.
