  • Patent number: 9023468
    Abstract: A method of preparing a poly (ether ketone ketone) consisting essentially of the repeat unit: —Ar—O—Ar—C(?O)—Ar—C(?O)— wherein each Ar is independently an aromatic moiety is provided. The method may comprise the step of polymerising a monomer system in a reaction medium comprising: (a) a Lewis acid; and (b) a controlling agent comprising an aromatic carboxylic acid, an aromatic sulphonic acid, or a derivative thereof.
