A modified Friedel–Crafts synthesis has been used to make a variety of aromatic ether–ketone–‘X’(EKX) polymers. The ‘X’ groups incorporated were: imide, amide, sulphone, ester, azo, quinoxaline, aliphatic, fluoroaliphatic and fluoroaromatic. Some properties of these EKX polymers are reported and discussed.
