    Abstract: Metallized polyimide composites are prepared by depositing an electrolytic layer of metal onto an electrolessly-applied metal layer which is disposed on and chemically bonded to a polyimide substrate, the electrolytic metal layer being deposited from an electrolytic bath containing

    A. about 50 to about 275 grams per liter of an aqueous acidic metal electrolyte,
    B. about 30 to about 120 grams per liter of a strong acid,
    C. about 20 to about 500 parts per million of halide ions,
    D. about 0.5 to about 6% by volume of at least one organic chemical additive comprising an organic levelling agent, an organic brightener or a mixture of the foregoing.

    These composites are characterized by improved surface characteristics and improved adhesion between the electroless metal layer and the polyimide surface.

    Abstract: The invention is directed to molding foamable thermoplastic materials employing an insulated mold structure, in order to improve the surface quality of the foamed article. In an exemplary embodiment, a first insulation layer (26) is deposited on the core (12) and a second or primer layer (28) is deposited on the first layer which includes a suspension in metallic particles in a resin. A hard metal coating may be deposited over the second layer. Foamed thermoplastic articles formed using the molds have uniform surface quality, and high adhesion to metal coatings exhibiting good electrical properties.

    Abstract: Increases in surface resistivity of electroless nickel coatings on polycarbonate-containing substrates are inhibited by employing two electroless nickel plating solutions. The first solution is one which deposits a metal layer containing phosphorus, if any, in an amount up to 5% by weight and is used to deposit a layer at least 0.5 micron thick. The second solution is one which deposits a layer containing phosphorus in the amount of at least 5% and preferably at least 6% by weight. Another metal layer may be interposed between the two nickel layers.
