<p>A matrix resin such as a polycarbonate/polyester blend, a polycarbonate, a vinyl aromatic copolymer or an acrylate polymer or copolymer is admixed in a composition with poly(phenylene ether), and/or with a poly(phenylene ether) concentrate containing poly(phenylene ether), polystyrene, a vinyl aromatic copolymer, polyamide, polycarbonate, polyester, poly(alkyl acrylate), and/or poly(alkyl methacrylate). The compositions may also optionally contain additional vinyl aromatic copolymer as a separate component, impact modifiers, thermoplastic molding materials including polystyrene, polyolefin, polyamide, poly(vinyl chloride), polyurethane, poly(methyl methacrylate) and polyacetal, and conventional additives such as dyes and pigments. The compositions when molded, particularly when the poly(phenylene ether) content thereof is low (for example, 5 weight percent or less) show a desirably low gloss, and a desirable balance of other properties.</p> |
