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.

Abstract: A method for desalinating a salt-containing polymer is provided. The salt-containing polymer contains a polyaryl ether and a salt. The method includes the steps of mechanically increasing the surface area of the salt-containing polymer to obtain a salt-containing polymer of increased surface area, and contacting the salt-containing polymer of increased surface area with an extractant to obtain a desalinated polymer containing the polyaryl ether, and a salt-containing extractant containing the extractant and the salt.
