Abstract
Abstract THERE ARE PROVIDED COMPOSITIONS COMPRISING (A) A POLYPHENYLENE ETHER IN COMBINATION WITH A STYRENE RESIN AND (B) AN INTERPOLYMERIZATION PRODUCT OF AN ACRYLIC ESTER WITH A POLYISOPRENE. THE ADDITION OF THE INTERPOLYMERIZED ACRYLIC ESTER-POLYISOPRENE TO COMPOSITIONS OF POLYPHENYLENE ETHERS-POLYSTYRENES PROVIDES UNEXPECTED IMPROVEMENTS IN TOUGHNESS IN PARTS MOLED FROM THE COMPOSITIONS AND IN THEIR RESISTANCES TO GASOLINE. SUCH PROPERTIES ARE IMPROVED WITH SUBSTANTIAL ENHANCEMENT IN GLOSS AND SURFACE APPEARANCE.
