Abstract
Abstract THE BRIGHTNESS OF METAL PLATING UPON POLYSTYRENE MOLDED PARTS IS GREATLY ENHANCED BY BLENDING A SMALL QUANTITY OF LESS THAN ABOUT 15% OF A TERPOLYMER OF ACRYLONITRILE, BUTADIENE AND STYRENE WITH THE POLYSTYRENE BEFORE MOLDING. THE POLYSTYRENE BEFORE BLENDING PREFERABLY CONTAINS A SMALL QUANTITY OF PREFORMED RUBBER IN THE POLYMER.
