A method of preparing a poly(arylene ether) includes oxidatively polymerizing a monohydric phenol in solution, concentrating the solution by removing a portion of the solvent to form a concentrated solution having a cloud point, Tcloud, adjusting the temperature of the concentrated solution to at least about (Tcloud-10° C.), and combining the concentrated solution with an anti-solvent to precipitate the poly (arylene ether). The method reduces the formation of undesirably fine particles in the product poly(arylene ether). |
