Production of an aromatic polyketone by reacting in the presence of a fluoroalkane sulphonic acid the reactants selected from: (a) a mixture of (i) at least one aromatic diacyl halide WOC-Ar-COW where -Ar'- is a divalent aromatic radical, W is halogen and COW is an aromatically bound acyl halide group, which diacyl halide is polymerizable with the at least one aromatic compound of (ii), and (ii) at least one aromatic compound H-Ar'-H where -Ar'- is a divalent aromatic radical and H is an aromatically bound hydrogen atom, which compound is polymerizable with the at least one diacyl halide of (i); (b) at least one aromatic monoacyl halide H-Ar''-COW where -Ar''- is a divalent aromatic radical and H, W, and COW are as defined in (a), which monoacyl halide is self-polymerizable; and (c) a combination of (a) and (b).
