Abstract
Abstract ELECTRICALLY NON-CONDUCTIVE ORGANOPOLYMERIC SURFACES ARE PREPARED FOR ELECTROLESS PLATING BY INCLUDING IN THE ORGANOPOLYMERIC SURFACES AN EXTRACTABLE FILLER AND EXTRACTING THE FILLER FROM THE SURFACE PRIOR TO PLATING. IMPROVED ADHERENCY BETWEEN THE ELECTROLESSLY DEPOSITED METAL PLATE AND THE SURFACE IS EFFECTED.
