A matrix resin, such as a polycarbonate/polyester blend, a polycarbonate, a vinyl aromatic copolymer, or an acrylate polymer or copolymer, is blended into a composition with a polyphenylene ether, and/or with a polyphenylene containing polyphenylene ether, polystyrene, aromatic vinyl copolymer, polyamide, polycarbonate, polyester, polyalkyl acrylate, and/or polyalkyl methacrylate. The compositions may also optionally contain additional vinyl copolymer as a separate component, impact modifiers, thermoplastic molding materials including polystyrene, polyolefin, polyamide, polyvinyl chloride/polyurethane, polyvinyl methyl and polyacetal, and ordinary additives such as dyes and pigments. The compositions, when molded, and especially when the polyphenylene ether content is low (eg, 5% by weight or less), exhibit reduced gloss, and a good balance of other properties. |
