ABSTRACT:
The peel strength of metal-clad polymers may be increased by treating a polymer such as polysulfone with a gas plasma prior to the deposition of the metal thereon. The gas plasma is provided for by the introduction of a gas such as helium, argon, etc. over the surface of the polymer while said polymer is in an electric field in which the power may range from about 50 to about 15,000 watts.
