Charlie F. Yancey has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Composition including a catalytic metal-polymer complex and a method of manufacturing a laminate preform or a laminate which is catalytically effective for subsequent electroless metallization thereof
    Patent number: 5985785
    Abstract: The inventive method provides a simple and economical method of manufacturing a laminate which is catalytically effective for subsequent electroless deposition thereon of metals, such as copper, and which is useful as a substrate for printed circuit boards. Advantageously, the inventive method provides an improved laminate having a substantially uniform distribution of finely divided catalytic metal, Me.sub.(0), within a crosslinked synthetic polymer impregnant. A catalytic metal-polymer complex is formed between a salt of a catalytic metal and a crosslinkable synthetic polymer, optionally containing a monomeric reactive diluent, to provide a concentrate which may be worked up into an impregnating composition for impregnating reinforcing material therewith. The complex is then destroyed and the catalytic metal, such as palladium-II, reduced to elemental metal, such as palladium metal, Pd.sub.(0), during or after crosslinking of the polymer system under conditions effective for crosslinking the polymer system.
    Type: Grant

    Date of Patent: November 16, 1999
    Assignee: Alpha Corporation
