Fluoroelastomer composition having excellent processability and low temperature properties
 Fluoroelastomers containing copolymerized units of vinylidene fluoride, perfluoro(alkyl vinyl)ether, 2-hydropentafluoropropene, and, optionally, tetrafluoroethylene, and having an iodine atom present at some polymer chain ends, exhibit excellent low temperature properties and processability when dual cured with both polyhydroxy compounds and organic peroxides.
