    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.
