ILLUSTRATIVELY, THE ADDITION OF AN ACRYLIC RESIN MODIFIED BUTADIENE RUBBER-ACRYLONTRILESTYRENE RESIN TO POLYPHENYLENE ETHERS OR MIXTURES OF POLYPHENYLENE ETHERS AND POLYSTYRENES PROVIDES UNEXPECTED IMPROVEMENTS IN TOUGHNESS IN PARTS MOLDED FROM THE COMPOSITIONS, AND IN THEIR RESISTANCE TO GASOLINE. SUCH PROPERTIES ARE IMPROVED WITHOUT SUBSTANTIALLY IMPAIRING GLOSS OR SURFACE APPEARANCE.
