  • Polymers comprising benzotriazole for use in optical devices
    Patent number: 7750112
    Abstract: The present invention relates to polymers comprising benzotriazole containing repeating units. Optical devices, comprising the polymers of the present invention, can show significant advantages in color purity, device efficiency and/or operational lifetime. In addition, the polymers can have good solubility characteristics and relatively high glass transition temperatures, which facilitates their fabrication into coatings and films that are relatively thin, thermally stable, and relatively free of defects.
    Type: Grant
    Filed: April 26, 2004
    Date of Patent: July 6, 2010
    Assignee: Ciba Specialty Chemicals Corp.
    Inventors: Jonathan Rogers, Michael Robert Craig, Thomas Schäfer
  • Polymers for use in optical devices
    Patent number: 7649077
    Abstract: The present invention relates to polymers comprising diazine, especially pyrimidine, containing repeating units. Optical devices, comprising the polymers of the present invention, can show significant advantages in color purity, device efficiency and/or operational lifetime. In addition, the polymers can have good solubility characteristics and relatively high glass transition temperatures, which facilitates their fabrication into coatings and films that are relatively thin, thermally stable, and relatively free of defects.
