Abstract: The invention relates to a quasi-continuous process for the preparation of polyarylene ether ketones by Friedel-Crafts polycondensation of a reaction mixture containing… A. a monomer system comprising… (a) (1) an aromatic dicarboxylic acid chloride or phosgene and (2) a polynuclear aromatic compound containing two replaceable hydrogen atoms,… and/or… (b) a polynuclear, aromatic carboxylic acid chloride containing a replaceable hydrogen atom,… B. a Lewis acid,… C. if desired a Lewis base, and… D. an inert solvent. … The reaction mixture is polycondensed in a first zone with stirring to a maximum viscosity of 2000 mPa.s, subsequently conveyed through a second, vertical, unstirred zone in a graft flow by means of gas pressure, during which it is fully polycondensed, and finally discharged continuously.
