Abstract: A thermoplastic composition comprising a poly(arylene ether), a polyamide, a compatibilizing agent, and a polyester ionomer exhibits reduced moisture absorption, improved paint adhesion, and improved stability. Use of the polyester ionomer allows use of lower amounts of conductive fillers. The compositions of the present invention comprise an amount of a stabilizer package effective to enhance the morphological stability of the thermoplastic composition wherein the stabilizer package comprises at least one phenolic species in combination with at one thioester species, at least one one organo-phosphite species, or at least one thioester species in combination with at least one organo-phosphite species.
