  • Low dielectric constant allylics
    Patent number: 5708116
    Abstract: A reaction product of a liquid monomeric allyletherfluoroalkylene benzene d a liquid polymethylhydrosiloxane, which reaction product in a cured, solid state has dielectric constant below about 2.5.
    Type: Grant
    Filed: May 31, 1995
    Date of Patent: January 13, 1998
    Assignee: The United States of America as represented by the Secretary of the Navy
    Inventors: James R. Griffith, Henry S. W. Hu
  • Fluorinated resins with low dielectric constant
    Patent number: 5405677
    Abstract: A highly fluorinated benzene compound is reacted with acryloyl chloride to ield a fluorinated liquid product which is used to impregnate a reinforcing structure. Upon impregnation, the liquid material is polymerized at about 55.degree. C. to produce a reinforced polymeric structure, which can be a circuit board. The polymer has dielectric constant of about 2.1, which is very low compared to the polymers used presently.
    Type: Grant
