Abstract: A process for generating a carboxylic acid from a hydrolysable polymer containing the carboxylic acid includes i) depolymerizing the polymer by hydrolysis in an aqueous hydrolysis solution, to form a carboxylate; ii) optionally removing further monomeric constituents and any further soluble and/or insoluble impurities located in the hydrolysate solution; iii) transferring the hydrolysate solution into an anode compartment of an electrolysis device; iv) performing an electrolysis with the hydrolysate solution in the anode compartment by connecting the electrolysis device to a voltage source, with current flowing through the electrolysis device and ion exchange taking place between the liquids in the anode compartment and the cathode compartment, so that the liquid in the cathode compartment becomes alkaline and protons are formed in the anode compartment that protonate the carboxylate, causing the carboxylic acid to precipitate; and v) removing the carboxylic acid formed from at least part of the hydrolysate s
