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.
Claims15
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.
