Abstract:
A fluorine-containing graft copolymer, a preparation method therefor and the use thereof. The preparation method of the fluorine-containing graft copolymer comprises the following steps: reacting a compound as shown in formula (I) and a compound as shown in formula (II) in a first organic solvent under the action of a catalyst and a ligand at 20-30ºC under a protective atmosphere, so as to obtain a fluorine-containing graft copolymer as shown in formula (III) after complete reaction, wherein the structural formulas of the compounds as shown in formulas (I) and (II) and the fluorine-containing graft copolymer as shown in formula (III) are as follows: the compound as shown in formula (II) comprises a polyethylene glycol segment with alkynyl at the end, a = 4-8, b = 6-8, n = 1-20, and m = 3-22.
