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.
