Abstract: A process for preparing a polyarylene ether ketone comprises the following process steps: a) reaction of an aromatic dihalogen compound with a bisphenol and/or a halophenol in the presence of alkali metal and/or alkaline earth metal carbonate or hydrogencarbonate in a high-boiling aprotic solvent to give a polyarylene ether ketone, b) wet comminution and simultaneous preextraction of the solidified reaction mixture, c) extraction and filtration of the wet-comminuted product in a pressure suction filter and d) drying of the extracted product. This combination enables improved workup of the reaction mixture.

Abstract: A polyarylene ether ketone is prepared by adding an aromatic dihalogen compound and a bisphenol to a reactor and conducting a polycondensation reaction in the presence of one or more of an alkali metal carbonate and an alkaline earth metal carbonate in a high-boiling solvent; and again adding, during the course of the polycondensation, at least one of a bisphenol and an aromatic dihalogen compound in an amount to achieve a target molar mass of the polyarylene ether ketone.
