摘要： A reflective article includes an injection molded thermoplastic substrate, and a reflective metal layer disposed on a surface of the thermoplastic substrate. The injection molded thermoplastic substrate is prepared from a pre-blended composition including specific amounts of two poly(phenylene ether)s having different intrinsic viscosities, an atactic polystyrene, and, optionally, a hydrogenated block copolymer of an alkenyl aromatic compound and a conjugated diene. The reflective article is lighter and less costly than comparable reflective articles based on heat-resistant polycarbonates. Also described are a melt-blended composition derived from the pre-blended composition, and an injection-molded article prepared from the melt-blended composition.

摘要： A poly(phenylene ether)-based composition exhibiting improved resistance to decomposition after repeated exposure to high voltages is prepared by melt-blending specific amounts of a poly(phenylene ether), an organophosphate ester flame retardant, and a surface energy reducing agent. The composition includes no more than 30 weight percent of mineral filler. Also described is an injection molded article prepared from the composition.

摘要： A thermoplastic composition comprises particular amounts of a poly(phenylene ether)-poly(siloxane) block copolymer reaction product; a hydrogenated block copolymer of an alkenyl aromatic and a conjugated diene; tricalcium phosphate; and an organophosphate ester flame retardant. The composition can be particularly useful for use in battery pack insulation films or sheets.
