Abstract: A method for plating a high impact resistant plastic, particularly a polycarbonate substrate which has been modified with up to about 50 percent by weight of acrylonitrile-butadiene-styrene. The surface of the plastic is first conditioned with a halogenated organic solvent conditioner, preferably 1-3-dichloro-2-propanol, prior to the electrochemical deposition of the desired metal layer.

Abstract: The present invention presents a solid polymer electrolyte consisting of a multiphase polymer matrix and an electrolyte solution. The polymer matrix consists of a highly polar polymeric (HPP) phase impregnated with the electrolyte solution to form ion conducting channels, and a less polar polymeric (LPP) phase, constituting the support structure. Further, the invented solid polymer electrolyte may also include a second ion conducting channels, forming a multiphase microstructure in which the electrolyte solution is present around the LPP particles as a fine mesh-like network. The invention also presents two kinds of method for making such a solid polymer electrolyte. The first includes the steps of: making a multiphase polymer matrix; and impregnating the polymer matrix with an electrolyte solution.

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.

Abstract: The process of electroless plating of polymers containing units derived from at least one member of the group consisting of acrylonitrile, butadiene and styrene, is carried out in an environment free of chromium ions, by the sequential steps of roughening and activating the surface of the polymer by contacting the same with an aqueous solution of a concentrated sulfur acid, of concentrated nitric acid or of concentrated phosphoric acid, in the presence of noble metal ion and an oxidant selected from the group consisting of nitric acid, hydrogen peroxide and persulfates. This is followed by an aqueous suspension of Pd.sup.0 and then by the conventional chemical metallization.
