  • Block copolymers for optical data storage
    Patent number: 7018684
    Abstract: Block polymers suitable for the preparation of data storage media are disclosed. The media produced of the inventive of the polymers has thickness in the range of a few millimeters. In contrast with currently available materials that feature high optical density the inventive polymers feature increased dilution of dyes (decrease in optical density) and decrease in the holographic diffraction efficiency.
