    摘要: A method of preparing a poly(arylene ether) includes oxidatively coupling a monohydric phenol in a reaction solution at a reaction temperature that exceeds the cloud point temperature of the reaction solution. The oxidative coupling occurs in the presence of a metal complex catalyst, and when the catalyst includes an amine ligand, the method facilitates incorporation of the amine ligand into the poly(arylene ether) resin. The amine-incorporated poly(arylene ether) resins prepared by the method are useful in the preparation of higher molecular weight poly(arylene ether) resins and compatibilized blends of poly(arylene ether) resins with other thermoplastics.

    摘要: 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).

    摘要: A process for producing a poly(arylene ether) resins includes oxidatively coupling a monohydric phenol in the presence of a solvent and a catalyst to form a soluble poly(arylene ether) and an insoluble poly(arylene ether), separating the soluble poly(arylene ether) and the insoluble poly(arylene ether), and recycling the soluble poly(arylene ether). The process is particularly useful for synthesizing poly(arylene ether) copolymers in which the monomer compositions of soluble and insoluble copolymers may vary.
