Title:
FLUOROPOLYMER, COMPOSITION, OPTICAL FILM, LIQUID-CRYSTAL FILM, HARDCOAT FILM, AND POLARIZER
Document Type and Number:
WIPO Patent Application WO/2021/220676
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: a fluoropolymer capable of forming films excellent in terms of alignment property and homogeneity; a composition containing the fluoropolymer; and an optical film, a liquid-crystal film, a hardcoat film, and a polarizer which each include a layer formed from the composition. The fluoropolymer includes repeating units represented by general formula (I). In general formula (I), L1 represents a single bond or a divalent linking group, R1 represents a hydrogen atom, a fluorine atom, a chlorine atom, or an alkyl group having 1-20 carbon atoms, and R2 represents a group containing a fluorine atom.
