Abstract

A fluoroelastomer comprising a copolymer of fluoroolefin monomers selected from one or more of the group consisting of 2,3,3,3-tetrafluoropropene, 1,3,3,3-tetrafluoropropene and 1-chloro-3,3,3-trifluoropropene, and ethylenically unsaturated co-monomers; wherein the fluoroelastomer has a glass transition temperature (Tg) of from about −60° C. to about 53° C. A process of making the fluoroelastomer.
