Patent ID: 7449507

Claim:
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 1 and R 2 are independently C 1 -C 6 alkyl, phenyl, or aryl; R 3 is independently C 1 -C 10 alkylene, C 6 -C 10 arylene, C 6 -C 10 alkylarylene, or C 6 -C 10 arylalkylene; M is calcium, magnesium, aluminum, zinc or a combination comprising one or more of the foregoing; d is 2 or 3; f is 1 or 3; x is 1 or 2; each R 4 and R 5 are independently a hydrogen group or a vinyl group of the formula —CR 7 ═CHR 8 ; R 7 and R 8 are independently hydrogen, carboxyl, carboxylic acid derivative, C 1 -C 10 alkyl, phenyl, benzyl, or an aromatic substituted with a C 1 -C 8 alkyl; K is independently hydrogen or a 1/r metal of valency r and u has a value of 1 to 20; 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 6 ohm-cm, and wherein weight percent is based on the total weight of the composition.
