| 摘要 |
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 Ph1-PH1-O alone or with ketone containing or sulphone-containing units, where Ph1 is phenylene.
