  • Polyfluorinated epoxides and associated polymers and processes
    Patent number: 6653419
    Abstract: A method for producing partially fluorinated epoxides and corresponding polyether homopolymers of these polyfluorinated epoxides is described. Also described is a method for incorporating a fluoroalcohol functional group into a polymer as a pendant group. Certain perfluorinated olefins are also described. These polyfluorinated epoxides and the associated polymers and methods relating to them are useful components in photoresists, particulary in lithographic photoresists for use at low ultraviolet wavelengths (e.g., 157 nm).
