OPTICAL COMPENSATION FILMS BASED ON FLUOROPOLYMERS

摘要

An optical compensation film composition is disclosed herein having a polymer film and a substrate, wherein the polymer film has a positive birefringence greater than 0.005 throughout the wavelength range of 400 nm< ? <800 nm, the film having been cast from a polymer solution comprising a solvent and a polymer having a moiety of (I) wherein R1, R2 and R3 are each independently hydrogen atoms, alkyl groups, substituted alkyl groups, or halogens, wherein at least one of R1, R2 and R3 is a fluorine atom, and wherein R is hydrogen or a substituent on the styrenic ring.
