Abstract
Provided herein are perfluoro copolymers of a perfluoro dioxole monomer, a perfluoro dioxane monomer, and an optional perhalo monomer. Methods of making the perfluoro copolymers and methods of using the perfluoro copolymers are also disclosed.
Claims20
A perfluoro copolymer of a first monomer, a second monomer, and an optional third monomer,
- wherein the first monomer is a perfluoro dioxole compound,
- wherein the second monomer is a perfluoro compound of Formula I:
- wherein the R1 and R2 are each independently F or a C1-C4 perfluoro alkyl, provided that R1 and R2 are not the same, and
- wherein the third monomer is selected from:
- (a) a perhaloolefin wherein each halogen is fluorine or chlorine, provided that at least one half of the halogen atoms must be fluorine, or (b) a perfluoro(alkyl vinyl ether).
