A method of making a poly(phenylene ether) includes oxidatively polymerizing a combination of a phenolic monomer and a monofunctional phenylene ether oligomer in the presence of an organic solvent and a copper-amine catalyst. The method further includes terminating the oxidative polymerization to form a post-termination reaction mixture; combining an aqueous solution comprising a chelant with the post-termination reaction mixture to form a chelation mixture including an aqueous phase having chelated copper ion, and an organic phase having dissolved poly(phenylene ether); separating the aqueous phase and the organic phase; and isolating the poly(phenylene ether) from the organic phase.
