ABSTRACT:
Aromatic polyethers are produced by polycondensing monomers containing phenolic groups and aromatic halogen, at least some of the aromatic halogen-containing monomers being free of activating groups such as --CO-- or --SO--, in the presence of a copper-containing catalyst and of a basic alkali metal compound present in stoichiometric excess relative to phenolic groups and copper. The products include new polyethers, particularly containing the repeating unit Ph.sup.1 --PH.sup.1 --O alone or with ketone containing or sulphone-containing units, where Ph.sup.1 is phenylene.
