Abstract
The present invention relates to a process for preparing an elastomeric ethylene-hexafluoropropylene copolymer with excellent vulcanization properties, which comprises emulsion polymerizing ethylene, hexafluoropropylene and when in demand, a monomer copolymerizable therewith in a aqueous medium at a low temperature of −20° C. to 40° C. using a radical polymerization initiator.
