Abstract
A thermoplastic composition comprising a compatibilized blend of poly(arylene ether) and polyamide; a reinforcing fiber; and an electrically conductive filler. Greater than 50 weight percent of the polyamide, based on the total weight of the polyamide, is polyamide-6. The thermoplastic composition is useful in articles that are painted by electrostatic painting.
