Sulfonated block copolymers (SBCs) are coagulated from SBC solutions in one or more organic solvents, including reaction mixtures obtained in the sulfonation process, by a process in which the SBC solution is ejected into or onto water provided that no steam is added to the SBC solution prior to ejection and provided that the ejection velocity as well as the water temperature and convection are controlled and balanced. The coagulation process is easy to implement and avoids or at least diminishes problems due to foaming and the formation of micro dispersions of the SBC which cannot be separated successfully or easily by conventional filtration or centrifuging.
