- Example 2 to 4 in which a part of the monomer 3 was post-added to the emulsion and emulsion polymerization was performed, and Example 10 in which the fluorine-containing copolymer was washed with warm water and a polar solvent were not used. Even when compared with Example 1, it is easier to elute with a component having a relatively shorter retention time, that is, with the liquid. ⁇ 02020/175197 38 ⁇ (: 171?2020/005883
- the fluorine-containing copolymer of the present invention and the composition containing the same are useful as a water/oil repellent composition, a release agent, a release agent, and the like.
