Process for production of aromatic polyethers.

摘要

An improved process for producing aromatic polyethers by condensation polymerizing aromatic dihydroxy compounds represented by the general formula: HO-Ar-OH and aromatic dichloro compounds represented by the general formula: Cl-Ar<1>-Y-Ar<2>-Cl, or condensation polymerizing monohydroxymonochloro aromatic compounds represented by the general formula: HO-Ar<1>-Y-Ar<2>-Cl in the above formulae, Ar, Ar<1>, Ar<2> are as defined in the specification) in the presence of alkali metal compounds comprising a combination of alkali metal carbonates comprising carbonate and/or hydrogencarbonate of an alkali metal, e.g., potassium, and alkali metal fluorides. In accordance with the present process, high molecular weight aromatic polyethers can be efficiently produced from aromatic chloro compounds which are inexpensive and easily available.
