Abstract: The present invention relates to a process for preparing a polyaryl ether by reacting components (a1) and (a2) in the presence of a carbonate compound (C) to obtain a salt-containing polymer (SP) comprising the polyaryl ether and a salt (S). After the reaction, the salt (S) is extracted from the salt-containing polymer (SP) to obtain a desalinated polymer (DP) comprising the polyaryl ether.
