Abstract
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 density may range from about 3.8 x 10 -3 watts/cm 2 to about 1.2 x 10 -1 watts/cm 2 .
