Abstract: A method for plating a high impact resistant plastic, particularly a polycarbonate substrate which has been modified with up to about 50 percent by weight of acrylonitrile-butadiene-styrene. The surface of the plastic is first conditioned with a halogenated organic solvent conditioner, preferably 1-3-dichloro-2-propanol, prior to the electrochemical deposition of the desired metal layer.

Abstract: A process for metal plating a high impact, high temperature plastic suitable for forming trim elements of an automobile. The process is particularly directed to plating an elastomer-modified PPA resin, and entails closely controlled process steps that include selectively etching the elastomer and the PPA matrix with a solution containing chromic acid, then effectively removing from the substrate any retained chromium which would adversely affect the ability of metal plating to adhere to the substrate, and thereafter protecting the substrate from attack by sulfuric acid. The process is particularly effective for electroplating a PPA resin modified with about five to about 30 weight percent EPDM.
