| titleOfInvention | Preparation method of fluorine-containing polymer |
| abstract | The invention discloses a preparation method of fluorine-containing polymer. The fluorine-containing polymer is obtained through the emulsion polymerization of fluorine-containing olefins monomer in the aqueous medium of fluorine-containing surfactant under the existence of initiator, wherein the weight percentage concentration of the fluorine-containing surfactant in the aqueous medium is 0.01-1%, the weight percentage concentration of the initiator in the aqueous medium is 0.001-1%, the reaction temperature is 10-120 DEG C and the pressure is 1-6.5MPa, and the reaction time is 3-15hours. The fluorine-containing surfactant satisfies a general formula shown in the specifications, wherein a is equal to 0 or 1; b is equal to 1 or 2; c is equal to 1, 2 or 3; d is equal to 1 or 2; X is C1, F or CF3; Y is H, F or CF3; and M is carboxylate or sulphonate. According to the method, perfluoro caprylic acid and derivatives thereof are not used in the method, so the method is environment-friendly; the preparation process can be conducted under wild temperature and pressure condition without affecting the reaction ratio of the polyreaction; and polymer powder with multiple grain sizes can be obtained, and thereby fluorine-containing polymer products at various grades can be prepared. |
