Claim:
1. A fluoroelastomer comprising a copolymer consisting essentially of: (a) one or more fluoroolefin monomers selected from the group consisting of 2,3,3,3-tetrafluoropropene, 1,3,3,3-tetrafluoropropene, 1-chloro-3,3,3-trifluoropropene, and mixtures thereof, and (b) one or more ethylenically unsaturated co-monomers; wherein the ethylenically unsaturated co-monomer is selected from the group consisting of ethylene, propene, cyclopentene, cycloheptene, cyclooctene, and mixtures thereof; wherein all the ethylenically unsaturated co-monomers together are present in the copolymer in an amount of from about 30 to about 95 mole percent of all the monomers of the copolymer; and wherein the fluoroelastomer has a glass transition temperature (Tg) of less than 0° C.
