Composition and process for conditioning the surface of polycarbonate resins prior to metal plating.

摘要

The coverage and adhesiveness of metal plating to polycarbonate resin is enhanced by treating the resin prior to etching with a swellant composition comprising a compound represented by the general formula: R1 (OCn H2n)m O - R2 wherein R1 and R2 are independently selected from the group consisting of aryl groups and alkyl groups of 1-4 carbon atoms, n is 2 to 4 and m is 1 to 5. The subsequent etching is then preferably effected using a highly alkaline composition such as a solution containing grater than about 100 g/l NaOH although other etchants such as chromic acid may also be used.
