Abstract: 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, and combining the concentrated solution with an anti-solvent to precipitate the poly (arylene ether), wherein the concentrated solution has a temperature of at least about (Tcloud-10° C.) immediately before it is combined with the anti-solvent. The method reduces the formation of undesirably fine particles in the product poly(arylene ether).

Abstract: Poly(arylene ether) resins having intrinsic viscosities greater than about 0.8 dL/g are produced in the reaction of a phenol with oxygen in the presence of an organic solvent and a metal complex catalyst, the phenol concentration being about 5 to about 15 weight percent of the sum of phenol and solvent, and the molar ratio of metal in the metal complex catalyst to the phenol being about 1:100 to about 1:200.
