    Abstract: In order to prepare polyarylene ether ketones by Friedel-Crafts polycondensation, a reaction mixture comprising A. a monomer system, B. a Lewis acid, C. optionally a Lewis base and D. an inert solvent is polycondensed in two reaction zones and discharged in plug flow from the second reaction zone and formulated. In this process, the reaction mixture is polycondensed in the first reaction zone with stirring to a viscosity of about 2000 mPa.s, transferred into the second reaction zone and discharged therefrom by means of an inert solvent or by means of an inert gas saturated with the solvent under a pressure of from about 6 to 65 bar, preferably even 10 to 25 bar, where the conveying pressure is reduced in at least two steps and the pressure reduction in the first step is at most 20%.
