ABSTRACT:
There are disclosed a process for producing an aromatic (poly)etherketone or an aromatic (poly)ethersulfone having an ether group represented by the formula --Y--Ar--O--Ar--Y-- which process comprises reacting an aromatic halogen compound having at least one active halogen group represented by the formula --Y--Ar--X, where Y denotes a ketone group or a sulfone group; Ar denotes a phenylene group or a nuclear-substituted product thereof; and X denotes a halogen atom which is bonded at the ortho- or para-position relative to Y, with a specified salt of an alkali metal, and an aromatic polyetherketone polymer which has a repeating unit represented by formula (I) ##STR1## and which has a crystalline melting point not lower than 390.degree. C. and an intrinsic viscosity of 0.7 to 2.0 dl/g (sulfuric acid at 25.degree. C.).
