| titleOfInvention | A kind of without perfluoro caprylic acid or the fluoropolymer of perfluorooctane sulfonate |
| abstract | The invention discloses a kind of without perfluoro caprylic acid or the fluoropolymer of perfluorooctane sulfonate, being obtained the fluoropolymer without perfluoro caprylic acid or perfluorooctane sulfonate in the case of poly-polyfluoroalkoxy ether acid is as emulsifying agent after liquid phase polymerization by one or more fluorinated monomers, described poly-polyfluoroalkoxy ether acid is the poly-polyfluoroalkoxy ether acid emulsifying agent of end group band halogen or hydrogen.Its technical scheme has related generally to the improvement in terms of three below: (1) selects poly-polyfluoroalkoxy ether acid and salt replacement PFOA/ PFOS thereof as fluorine-containing emulsifier, can be effectively applied to the aqueous emulsion polymerization of fluorinated monomer；(2) fluoropolymer prepared is without perfluoro caprylic acid or perfluorooctane sulfonate, meets environmental requirement；(3) meet cost accounting, do not increasing manufacturing facilities and the output per single reactor of equipment can be greatly improved in the case of personnel, simultaneously, moreover it is possible to improving the production target such as polymerization time, polymerization yield rate. |
