    摘要： 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.

    摘要： 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.
