  • Functionalized halogenated polymers for microencapsulation
    Patent number: 8361620
    Abstract: The present invention is directed to a novel reactive protective colloid system suitable for stabilizing an electrophoretic display in which a halogenated solvent, particularly a fluorinated, more particularly a perfluorinated, solvent, or a mixture thereof, is used as the dielectric solvent.
    Type: Grant
    Filed: February 13, 2006
    Date of Patent: January 29, 2013
