  • Substantially amorphous polyolefins useful as pressure-sensitive adhesives
    Patent number: 4186258
    Abstract: The invention relates to a process for the treatment of substantially amorphous polyolefins to provide permanently tacky, low viscosity materials which have useful pressure-sensitive adhesive properties. These permanently tacky amorphous polyolefin homo- and copolymers, as well as blends of such amorphous polyolefins with crystalline polyolefins containing up to 20 weight percent crystalline polyolefin, are novel pressure-sensitive adhesives.
    Type: Grant
    Filed: November 2, 1978
    Date of Patent: January 29, 1980
    Assignee: Eastman Kodak Company
    Inventors: Robert R. Schmidt, III, Jerry D. Holmes
