1. A composition comprising:
15 to 65 weight percent of a poly(arylene ether);
30 to 85 weight percent of a polyamide;
1 to 20 weight percent of an electrically conductive filler;
1 to 15 weight percent of an impact modifier comprising one or more of a block copolymers containing alkenyl aromatic repeating units, wherein the block copolymer is selected from the group consisting of polystyrene-polybutadiene, polystyrene-poly(ethylene-propylene), polystyrene-polyisoprene, poly(α-methylstyrene)-polybutadiene, polystyrene-polybutadiene-polystyrene, polystyrene-poly(ethylene-propylene)-polystyrene, polystyrene-polyisoprene-polystyrene and poly(alpha-methylstyrene)-polybutadiene-poly(alpha-methylstyrene), polystyrene-poly(ethylene-propylene-styrene)-polystyrene, and combinations of two or more of the foregoing block copolymers; and
5 to 25 weight percent of a phosphinate comprising one or more phosphinates of formula II, III, or IV
