  • Patent number: 10556973
    Abstract: Disclosed is a process for making nitrated styrenic fluoropolymers having various degrees of substitution. The nitrated styrenic fluoropolymer is capable of providing an exceptionally high birefringence ranging from 0.02 to 0.036. Further, the birefringence can be tuned by varying the degree of substitution (DS) of the nitro group on the styrenic ring to meet the need for optical compensation film applications. More particularly, the optical compensation films of the present invention are for use in an in-plane switching LCD (IPS-LCD) and OLED display.
