Fluoroelastomers containing copolymerized units of vinyl esters

Fluoroelastomers are disclosed that comprise copolymerized units of a vinyl ester of the formula CH2-CHOC(O)R, wherein R is a C1-C4 alkyl group and at least one monomer selected from the group consisting of tetrafluoroethylene and a perfluoro(alkyl vinyl ether). The elastomers may further contain co...

More Information
Summary:Fluoroelastomers are disclosed that comprise copolymerized units of a vinyl ester of the formula CH2-CHOC(O)R, wherein R is a C1-C4 alkyl group and at least one monomer selected from the group consisting of tetrafluoroethylene and a perfluoro(alkyl vinyl ether). The elastomers may further contain copolymerized units of a hydrocarbon olefin such as ethylene or propylene. Optionally, fluoroelastomers of the invention may contain copolymerized units of a cure site monomer or a cure site monomer. Pendant ester groups on the fluoroelastomer may be at least partially saponified.
