  • Process of metal plating on plastics
    Patent number: 4148945
    Abstract: The thermoplastic polymer employed in this invention is a rubber modified unsaturated carboxylic acid or anhydride containing polymer which is prepared by polymerizing the monomers in the presence of the rubber in a finely divided form. The surface to be metallized is first aminated with aqueous hydroxylamine or hydrazine, then treated with a noble metal salt solution and thereafter treated with a reducing agent, as needed, to produce a metallized surface having a resistance of 100 ohms/sq. or less. The metallized surface can then be further plated by conventional means.
