Abstract: THERMOPLASTIC MOLDING COMPOSITION CONSISTING OF A RIGID COMPONENT A AND AN ELASTOMERIC COMPONENT B. COMPONENT A IS A SOLUTION OR SUSPENSION GRAFT POLYMER OF STYRENE AND ACRYLONITRILE ON A BUTADIENE RUBBER. COMPONENT B IS AN EMULSION GRAFT POLYMER OF STYRENE AND ACRYLONITRILE ON AN ACRYLIC ESTER RUBBER. THE MOLDING COMPOSITIONS ARE CHARACTERIZED BY HIGH IMPACT RESISTANCE AT ROOM TEMPERATURE, GOOD RIGIDITY AND SATISFACTORY IMPACT RESISTANCE AT LOW TEMPERATURES. THEY MAY BE USED, FOR EXAMPLE, IN THE MANUFACTURE OF PLASTICE PARTS FOR AUTOMOBILES.
