Abstract:
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 wherein R wherein the electrically conductive filler comprises electrically conductive carbon black, carbon nanotubes, electrically conductive carbon fibers, or a combination of two or more of the foregoing; wherein the composition has a specific volume resistivity less than or equal to 10 wherein weight percent is based on the total weight of the composition.
