A composition includes specific amounts of a poly(phenylene ether), a rubber-modified polystyrene, an organophosphate ester, and polymerized acrylonitrile residue. When combusted in air, the composition yields a specific amount of ash. The composition can be prepared using a post-consumer recycled rubber-modified polystyrene that contains as impurities acrylonitrile copolymer and a metal oxide pigment that survives combustion of the composition. The composition is useful for molding large, flat parts, such as back panels for flat screen televisions. |
