A composition includes specific amounts of a virgin poly(arylene ether) resin and a rubber-modified polystyrene that is preferably derived from post-consumer recycling. The composition includes about 0.2 to about 1.5 weight percent of polymerized acrylonitrile residue that can originate as a contaminant in the recycled rubber-modified polystyrene. The composition avoids the need for compatibilizing agents required by related compositions.
