Beiträge zur galvanisierung von polymeren, 10. Metallisierung von copolymeren aus acrylnitril und butadien nach vorbehandlung mit ozon

Copolymers containing acrylonitrile and butadiene can be coated with metal electroless. There is only a small influence on the metal-to-polymer-adhesion with the time of treatment with ozone. The adhesion increases with the content of acrylonitrile and with the molecular weight of the polymer. Peel strength values have been measured up to 150 N/25 mm because of the cohesive fracture inside the polymer. The highest values of adhesion have been measured on samples having nearly the same values of the critical surface tension like those of the electroless deposited nickel-layer. Caverns supporting a mechanical staying of the metal have not been observed.
