Richard E. Peavy 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).

  • Fluoroalkene/hydrochlorofluorocarbon telomers and their synthesis
    Patent number: 5552500
    Abstract: The invention relates to fluorotelomers, their synthesis by free radical-initiated telomerization of fluoroalkenes (e.g. TFE) in which hydrochlorofluorocarbons (HCFC's) are used both as telogens and as solvents, and dispersions of the fluorotelomers in HCFC's. The fluorotelomers are normally solid, essentially non-distillable and highly crystalline, and their dispersions exhibit excellent lubricant properties and stability under normal usage and have a negligible impact on the environment compared to conventional telomer dispersions.
    Type: Grant
    Filed: April 24, 1995
    Date of Patent: September 3, 1996
    Assignee: E. I. Du Pont de Nemours and Company
