    摘要: The invention relates to a method of forming a polyphenylene ether resin containing residual aliphatic unsaturation. A polyphenylene ether is reacted with a capping agent in a solvent to form the polyphenylene ether resin containing residual aliphatic unsaturation, which is precipitated from solution by combining the solution with an antisolvent. The precipitated polyphenylene ether resin containing residual aliphatic unsaturation has lower levels of residual impurities than the same compound isolated by devolatilization.

    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.

    摘要: A flame retardant polyamide fiber is prepared from a composition containing specific amounts of a polyamide, a poly(phenylene ether), a flame retardant that includes a metal dialkylphosphinate, and a compatibilizing agent. The composition used to form the fiber can be prepared in a process that includes melt blending a portion of the polyamide with all the other ingredients to form an intermediate composition, and then melt blending the intermediate composition with the remainder of the polyamide. The composition has small disperse phase particles that facilitate its use to melt spin fibers.

    摘要: A composition is prepared by oxidative copolymerization of specific amounts of 2,6-dimethylphenol, 2,3,6-trimethylphenol, and a hydroxyaryl-terminated polysiloxane. The composition exhibits an increased heat resistance relative to a corresponding composition prepared by copolymerizing 2,6-dimethylphenol and hydroxyaryl-terminated polysiloxane, without 2,3,6-trimethylphenol. The composition is useful as a flame-retardant additive in polymer compositions that require high heat resistance.

    摘要: A piston guide ring for use in a piston-cylinder assembly includes a compatibilized polyamide-poly(arylene ether) blend. The compatibilized polyamide-poly(arylene ether) blend includes about 35 to about 95 parts by weight polyamide and about 5 to about 65 parts by weight poly(arylene ether), based on 100 parts by weight total of the polyamide and the poly(arylene ether). The piston guide rings provide improved compressive strength at elevated operating temperatures, more isotropic mold shrinkage, and reduced moisture absorption compared to piston guide rings prepared from polyamide.
