  • Patent number: 7148300
    Abstract: A compound is prepared, suitable for forming fluoroelastomers, having the unique features of a low glass transition temperature and desirable permeation resistance. The compound generally comprises two primary components. The first component is an amorphous copolymer including interpolymerized units derived from one or more perfluorinated ethers. The second component is a curable component including at least one filler having at least 10 parts per 100 parts of the first component. Upon vulcanization the resulting elastomeric compound has desirable physical characteristics as indicated by the durometer, the retraction at lower temperatures (TR-10) and permeation resistance.

  • Patent number: 6730760
    Abstract: A method of making a curable fluoroelastomer is disclosed. The method comprises the steps of preemulsifying at least one perfluorovinylether in water, and copolymerizing the preemulsified perfluorovinylether with a gaseous fluorinated monomer in the presence of a cure site monomer. The method provides a fluoroelastomer having a glass transition temperature of less than −10° C. Also disclosed is a fluoroelastomer that consists essentially of a perfluorovinylether of formula (I) as defined below, a cure site component, perfluoromethylvinylether, and tetrafluoroethylene and/or chlorotrifluoroethylene.

  • Patent number: 6255536
    Abstract: 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.

  • Patent number: 6255535
    Abstract: The present invention describes a novel process for the preparation of perfluoro allyl ethers. The process involves providing a hydrogen-containing precursor comprising at least one 1,2-dichloro alkyl ether moiety, fluorinating the precursor to provide a perfluorinated intermediate, and dechlorinating the perfluorinated intermediate to the corresponding perfluorinated ether. A reaction product of a perfluorinated olefin and an allyl ether may also be used as a precursor. Such a reaction product is chlorinated before the fluorination step. Perfluoro vinyl or allyl ethers may be used in place of the perfluorinated olefin. Novel perfluoro alkoxy compounds are also described.
