Abstract:
1. A composition comprising a poly(arylene ether) a polyamide; an electrically conductive additive; and a polymeric impact modifier, wherein the polyamide comprises greater than or equal to 25 weight percent, based on the total weight of the polyamide, of a polyamide having a melt temperature within 20% of the glass transition temperature of the poly(arylene ether); wherein the composition has a melt volume rate less than or equal to 15 cubic centimeters per 10 minutes as determined by ISO 1133 performed at 300° C. with a load of 5 kilograms when the composition moisture content, at the time of testing, is less than or equal to 0.05 weight percent (wt %), based on the total weight of the composition, and further wherein the composition demonstrates less than or equal to 0.0150 grams of composition buildup on the die face per minute of running time per meter of die opening perimeter after extruding the composition at a steady state for five minutes at 260° C. and 100 rotations per minute (rpm) on a 19 millimeter diameter single screw extruder through a rectangular slit die having a width of 102 millimeters (mm), an opening height of 2 mm and a depth of 29 mm with a die set temperature of 280° C. and further wherein no cooling means is applied to the extruded composition until the composition is greater than or equal to 100 millimeters from the die face and the composition has a flow rate through the die of 4.5 to 5.5 kilograms per hour as determined by weighing the extruded composition that has gone through downstream uptake reels over a known amount of time.
