Abstract:
Fluoroelastomers are disclosed that comprise copolymerized units of vinylidene fluoride and a vinyl ester of the formula CH 2 =CHOC(O)R, wherein R is a C 1 -C 4 alkyl group. In one embodiment of the invention, the fluoroelastomers further comprise copolymerized units of a perfluoro(alkyl vinyl ether) and, optionally, tetrafluoroethylene. In another embodiment, the vinylidene fluoride/vinyl ester fluoroelastomers further comprise hexafluoropropylene. Optionally, fluoroelastomers of the invention contain copolymerized units of a cure site monomer.
