| titleOfInvention | A kind of method of perfluorovinyl ethers modified polytetrafluoroethylene resin |
| abstract | The invention relates to the technical field of chemical production, and specifically relates to a method for modifying polytetrafluoroethylene resin with perfluorovinyl ethers; Fluorosulfonyl-based polyether emulsifiers partially replace perfluorooctanoic acid emulsifiers to reduce the use of perfluorooctanoic acid and prevent environmental pollution; fluorosulfonyl-containing polyethers increase the emulsification effect and optimize the particle size of polymer products The diameter is dispersed, which improves the mechanical strength and compressive capacity. |
