ABSTRACT:
A method of coating metal on a poly(aryl ether ketone) surface comprises treating the surface with a swelling agent, removing the swelling agent, etchinig the treated surface and then plating the etched surface with a metal using an electroless plating process. The process can be used to metal plate articles of poly(aryl ether ketones) of complex shapes, such as electrical connectors. Exceptional bond strength between the metal and the poly(aryl ether ketone) surface is obtained. Poly(aryl ether ketone) compositions, even those containing little, or no, glass or mineral fillers can be plated with a strongly adherent coating of plated metal using a process of this invention. The poly(aryl ether ketone) may contain additives such as pigments, fillers, stabilizers, reinforcing agents or the like. Blends of poly(aryl ether ketones) with other polymers, such as polyetherimides, fluoroelastomers, or the like, can be treated in accordance with this invention.
