  • Patent number: 8530552
    Abstract: A composition includes specific amounts of poly(phenylene ether), polymerized styrene residue, and polymerized acrylonitrile residue. The composition can be prepared using a recycled homopolystyrene that includes an acrylonitrile copolymer as an impurity. The composition largely preserves the desirable properties of a corresponding composition prepared from virgin resins without requiring chemical compatibilization of the poly(phenylene ether) and the acrylonitrile copolymer.
