Abstract
The invention provides a fluorine-containing graft copolymer, and a preparation method and use thereof. The method includes the following steps: under a protective atmosphere, reacting a compound of Formula (I) and a compound of Formula (II) in a first organic solvent in the presence of a catalyst and a ligand at 20-30° C., to obtain the fluorine-containing graft copolymers of Formula (III) after complete reaction. The compounds of Formulas (I) and (II), and the fluorine-containing graft copolymer of Formula (III) have a structural formula shown below: and the compound of Formula (II) comprises a polyethylene glycol segment and a terminal alkynyl group, wherein a=4-8; b=6-8; n=1-20; and m=3-22. In the present invention, a graft copolymer of a main-chain-type 'semi-fluorinated' alternating copolymer is obtained for the first time by post-polymerization modification using a reactive functional group contained in the main-chain-type “semi-fluorinated” alternating copolymers.
