Abstract

A thermoplastic composition includes a poly(arylene ether), a poly(alkenyl aromatic) resin, a polyolefin, a hydrogenated block copolymer of alkenyl aromatic compound and a conjugated diene having an alkenyl aromatic content of about 40 to about 90 weight percent, and an unhydrogenated block copolymer of an alkenyl aromatic compound and a conjugated diene. The composition exhibits excellent stiffness-impact strength balance, low property variability, and long melt hang time.
