The invention discloses a poly (phenylene ether) fiber, a method of forming, and articles therefrom. Small diameter poly(phenylene ether) fibers can be consistently formed from a composition comprising specific amounts of a poly(phenylene ether), a processing aid, and optionally a poly(alkenyl aromatic). The processing aid can be LLDPE, a petroleum resin, or combinations thereof. The processing aid can optionally further comprise a phosphite or phosphonate. Flame retardants are minimized or excluded from the composition. The fibers can be melt spun without entanglement or breakage, and this improved processability enables small diameter fibers to be formed. The resulting fibers can be used in reinforcing structures for printed circuit boards. 由包含特定量的聚(亚苯基醚)、加工助剂、和可选的聚(烯基芳香族化合物)的组合物可以不断形成小直径的聚(亚苯基醚)纤维。加工助剂可以是LLDPE、石油树脂、或它们的组合。加工助剂可以可选地进步包含亚磷酸酯或膦酸酯。阻燃剂从组合物最小化或排除。纤维可以在没有缠结或断裂的情况下熔融纺丝，并且该改善的可加工性允许形成小直径的纤维。得到的纤维可以用于印刷电路板的增强结构。
