ABSTRACT:
Polyaryletherketones are prepared by polymerization of a halogen-containing aryl ketone in the presence of a stoichiometric excess of a base and a copper salt. The halogen-containing aryl ketone may be 4-chloro-4'-hydroxybenzophenone. A basic copper salt may be used but the base used to provide the excess of base is an alkali metal hydroxide, carbonate or bicarbonate.
