fluorosurfactants, we synthesized eight amineoxides with a fluoroether chain. Their surface properties were evaluated and compared with perfluoroalkyl and hydrocarbon analogues. The surface tensions at critical micelle concentration (γcmc) for the eight amineoxides with a fluoroether chain were at a range from 15.5 to 23.0 mN/m, and γcmc of four fluoroether amineoxides were below 17 mN/m comparable to

The present invention describes a novel process for the preparation of perfluorovinyl ethers. The process involves providing a hydrocarbon precursor that may be partially halogenated, fluorinating the precursor to provide a perfluorinated intermediate, and converting the perfluorinated intermediate to the desired perfluorinated ether. Novel perfluorovinyl ethers are also provided.
