    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing polyarylene ether ketone with improved molar mass control and regulation.
    SOLUTION: The process for preparing the polyarylene ether ketone by reacting an aromatic dihalogen compound with a bisphenol in the presence of alkali metal and/or alkaline earth metal carbonate or hydrocarbonate in a high-boiling solvent, where the molar mass is established by, in the course of the polycondensation, bringing the molar mass to a target value by again adding a bisphenol or an aromatic dihalogen compound to the reaction.

    Abstract: PROBLEM TO BE SOLVED: To provide an improved washing method capable of clearly decreasing the residual content of salt and a reaction solvent (generally diphenyl sulfone) in the production of a polyarylene ether ketone without paying additional installation cost necessary in a washing method in a superatmospheric range.
    SOLUTION: A polyarylene ether ketone is produced by (a) a step to react an aromatic dihalide compound with bisphenol and/or a halogenated phenol in the presence of an alkali metal carbonate and/or an alkaline earth metal carbonate in an aprotic solvent having high boiling point to obtain the polyarylene ether ketone, (b) a step to crush the coagulated reaction mixture in the presence of water in wet state, (c) a step to wash with an organic solvent, (d) a step to wash with water and (e) a step to dry the washed product, wherein the wet-crushed reaction mixture having a residual moisture content of at least 1 mass% is supplied to the above two-stage washing step.

    Abstract: A process for preparing a polyarylene ether ketone is provided to manage and control the molar mass better, thereby setting the desired molar mass in a controlled manner. A process for preparing a polyarylene ether ketone comprises reacting an aromatic dihalogen compound with a bisphenol in the presence of an alkali metal carbonate and/or an alkaline earth metal carbonate in a high-boiling point solvent, wherein the molar mass in the reaction is established by bringing the molar mass to a desired value via further addition of a bisphenol or an organic halogen compound to the reaction in the course of polycondensation. Preferably, the dihalogen compound used in polycondensation is 4,4'-difluorobenzophenone, and the bisphenol used in polycondensation is hydroquinone.
