    Abstract: A polyamide-poly(arylene ether) composition is prepared by melt blending specific amounts of components including a polyamide, a poly(arylene ether), a hydrogenated block copolymer of an alkenyl aromatic monomer and a conjugated diene, a compatibilizing agent, and partially saponified ester of a C16-C36 aliphatic carboxylic acid and a C2-C12 aliphatic alcohol. The composition is useful for molding articles that have a significantly reduced incidence of the cosmetic defect known as “silver streaks”.
