摘要：

A thermoplastic composition includes specified amounts of a poly(arylene ether), a homopolymer of an alkenyl aromatic monomer, a polyolefin, a hydrogenated block copolymer, and an unhydrogenated block copolymer, but the composition is substantially free of any rubber-modified poly(alkenyl aromatic) resin. The composition provides high stiffness and high impact strength and is suitable for molding a variety of articles, including automotive underhood components.
