Abstract
Addition polymer substrates comprising structural groups derived from olefinic nitriles and conjugated dienes, especially ABS resin substrates, are treated with aqueous tetravalent cerium in a concentration of at least about 0.1 M, preferably with a tetravalent cerium solution, to improve adhesion to metal coatings subsequently deposited non-electrolytically; for example, by electroless deposition. The metallized articles are heat treated following metal deposition. Further metal coatings may be deposited, preferably followed by further heat treatment.
